PART 1
For 78 Saturdays, Andrés Montalvo bought 3 bottles of water in Chapultepec Park.
One for himself.
One for Mateo.
One for Renata.
And for those same 78 Saturdays, his 7-year-old twins hadn’t smiled even once.
Once, they had run through the park as if the world belonged to them. Mateo asked the weirdest questions about ants, airplanes, and traffic lights. Renata laughed with her whole face, dancing even when there was no music.
But since Sofía, their mother, died in a crash on the Periférico, the house in Lomas de Chapultepec had turned enormous, cold, and silent.
Andrés had money to spare. Hotels, construction companies, stocks, a chauffeur, security, staff. But none of that mattered when his children sat down to breakfast, untouched hotcakes cooling before them.
That Saturday, like every other, Andrés tried to lift their spirits.
“Do you want to go for ice cream afterward?”
Mateo adjusted his shirt as if he were a tiny adult.
“Ice cream doesn’t modify the emotional situation, Dad.”
Renata hugged her doll and gazed at the grass.
“I want to go home.”
Andrés felt the same blow to the chest he always did.
Then something absurd happened.
A young woman, in a blue dress with curly hair, came sprinting after a boy who had her bag.
“Hey! That bag is mine! No way!”
The thief didn’t get far.
Mateo, who always analyzed everything, raised his voice with tremendous seriousness:
“He’s heading towards the north exit! Stolen object alert!”
Renata, for the first time in months, let out a giggle.
Andrés stood frozen.
It wasn’t a laugh. It wasn’t full joy. But it was sound. Life. Something the house had forgotten.
The woman caught up with her bag thanks to a park officer and returned, panting.
“Thank you, Captain,” she said to Mateo. “And thank you to you too, Detective.”
Renata blinked.
“Detective?”
“Of course. You saw the escape route with your eyes. That counts.”
Renata looked down but smiled.
Andrés felt the world stop.
The woman introduced herself as Mariana. She worked at a reading center for children in the Roma neighborhood, a place called Letras de Colibrí.
Before she left, she handed Mateo a card.
“In case the rescue team wants to visit the base.”
That night, during dinner, Mateo discussed “urban robbery prevention,” and Renata drew Mariana with a giant bag and a huge smile.
Mrs. Lupita, the nanny who had been with them for years, stood at the door holding a pitcher of water, her eyes filled with tears.
Andrés didn’t know what to do.
The next day, at 6:42 AM, he found the twins dressed in the kitchen.
Mateo wore a tie.
Renata had her sweater on inside out.
“No,” Andrés said before they spoke.
“We haven’t requested anything,” Mateo replied.
Renata squeezed the card between her hands.
“Can you call her?”
Andrés wanted to say no. That a stranger couldn’t just waltz into their life like this. That no one could touch the place where Sofía still hurt.
But Renata whispered:
“She remembered our names.”
Andrés dialed.
The call rang 3 times.
“Letras de Colibrí, this is Mariana.”
Andrés swallowed hard.
Before he could say anything, Mariana let out a soft laugh.
“Is this the family of the bag operation?”
Renata lifted her face, and that little spark that appeared in her eyes left Andrés breathless.
No one could believe what was about to happen.
PART 2
The Colibrí Letters center resembled nothing in Andrés Montalvo's life.
There were no marble floors, no elegant receptionist, and no valet parking.
It was nestled between a bakery and an old stationery store, with walls painted by children, mismatched chairs, and a handmade sign that read, “Story Saturday, free entry.”
Andrés thought the twins would be scared by the noise.
There were kids screaming, crayons scattered, juice spilled, and a girl reading underneath a table as if it were the most normal thing in the world.
Mateo stood frozen.
Renata did too.
Then Mariana appeared.
“Mateo,” she said, as if she had been waiting for him.
He straightened his back.
“Renata.”
Renata smiled before she could hide it.
Andrés felt something inside him break, but not from pain. From relief.
Mariana read a story about an axolotl that wanted to fly. She made voices, dramatic pauses, and silly faces. The children burst into laughter.
When she asked what they thought, Mateo raised his hand.
“The axolotl had a biologically incorrect expectation.”
The room fell silent.
Mariana nodded seriously.
“True, but it had a heart to spare.”
Renata covered her face.
The kids laughed.
And so did Andrés.
His own laughter frightened him.
It had been two years since he had heard himself like that.
Then came the question box. Mariana pulled out papers written by the children and answered without mocking.
“Do dogs dream?”
“Sure. That’s why they move their paws as if chasing imaginary tacos.”
Laughter.
“Why do adults drink coffee if it makes them angry later?”
Andrés nearly choked.
Mariana pointed at him without looking.
“National mystery.”
More laughter.
Then she pulled out a folded paper.
Her smile dimmed a little.
“How long does sadness take to go away?”
The room fell silent.
Mateo stared at his shoes.
Renata squeezed her wrist.
Andrés felt his throat close up.
Mariana didn’t answer quickly.
She sat on the floor at the children’s level.
“Sadness doesn’t come with a clock,” she said. “Sometimes it stays for an afternoon. Sometimes it sits in a corner of your room and seems to live there.”
No one moved.
“But it weighs less when someone sits with you. Not when they say ‘get over it.’ Not when they force you to smile. Only when they say, ‘I’m here, I won’t leave you alone.’”
Mateo looked up.
Renata let a silent tear fall.
Andrés closed his eyes.
For the first time, someone explained what he hadn’t been able to say to his children.
From that day on, Colibrí Letters became part of their Saturdays.
Mateo made a notebook titled “Mariana File.” Renata pasted new drawings in her room. Some had faces. Others had the sun. One showed their mom Sofía holding hands with the three of them, and off to the side, further away, Mariana in her blue dress.
Andrés saw it and didn’t know whether to cry or be grateful.
Mrs. Lupita, on the other hand, did cry.
“Oh, sir, this house needed noise,” she said while pretending to clean a perfectly clean table.
But peace never arrives alone.
One afternoon, Doña Rosario, Mariana’s grandmother, appeared.
She entered the center wearing white sneakers, red lips, and a tray of homemade conchas, looking at everyone as if she were an inspector from the SEP.
She saw Mateo.
“You dress like an accountant from the SAT.”
Mateo frowned.
“I’m seven.”
“Worse yet, kid.”
Renata laughed until she could hardly breathe.
Doña Rosario sat next to Andrés without asking for permission.
“You're the sad dad with the expensive coat, aren’t you?”
Andrés froze.
“I suppose.”
“It shows, even at the back of your neck.”
Then she looked at Mariana, who was helping Renata color.
“My granddaughter knows about loss too. She lost her sister three years ago on the road to Cuernavaca. She was driving behind. She saw everything.”
Andrés stopped breathing.
Doña Rosario lowered her voice.
“She blamed herself for something she couldn’t control. Guilt is a tricky thing, young man. When it can’t find someone to blame, it invents one.”
Andrés looked at Mariana differently.
Not as the bright woman who had come to save his children.
But as someone who had also survived an impossible night.
“The weary recognize each other,” Doña Rosario said.
Andrés didn’t respond.
Because it was true.
As the months passed, the house changed.
Music returned on Sundays.
Renata started drawing eyes again.
Mateo stopped wearing a tie every day, though he kept it for “important events, investigations, and emotional emergencies.”
Andrés began calling Mariana during the week to ask her questions about the center, then to talk about books, then to talk about nothing at all.
The kids noticed before he did.
“Dad wears cologne on Saturdays,” Renata whispered.
Mateo wrote something down.
“Relevant information.”
“He likes Mariana.”
“The evidence suggests a high probability.”
The intervention was a disaster.
Renata called Mariana from Andrés’s cell while he was in the shower.
“My dad cooks on Sundays. He says he does it badly, but that’s a lie.”
“Renata, does your dad know you’re calling me?”
Silence.
“He also danced with my mom in the kitchen.”
Mariana didn’t speak.
Renata hung up.
Two days later, Mateo called from the house phone.
“I have additional information.”
“You’re worrying me, Mateo.”
“My dad claims he doesn’t dance. That’s false. I’ve observed foot movement during slow songs.”
Mariana smiled.
Then Mateo said something that broke her voice.
“When you’re around, he seems less sad.”
The following Saturday, the question box had two papers written in far too perfect handwriting.
Mariana opened the first one.
“What qualities make someone good to marry?”
Everyone turned to Mateo and Renata.
Renata looked at the ceiling.
Mateo put on an innocent face, but it was terrible.
Doña Rosario raised her hand.
“I’ll answer that one.”
“Grandma, please.”
“They must be kind, hardworking, not stingy, know how to apologize, love children, and not act all macho when they want to cry.”
Andrés turned red.
“I need air,” he murmured.
Mateo raised a finger.
“Avoidance confirms emotional tension.”
The room exploded in laughter.
But that same afternoon, while the kids played outside, Andrés found Mariana next to the bookshelves.
“Sorry for my kids.”
“You don’t have to apologize. They love you. And they’re trying to bring you back.”
Andrés stood still.
“Sofía filled the house with music,” he finally said. “I told her she exaggerated. After her death, silence felt like the only honest thing. But my children also started to live within my silence.”
Mariana looked at him with a tenderness that scared him.
“Maybe the house didn’t need to forget Sofía. Maybe it needed to start saying her name again without breaking.”
Andrés felt she had opened a door that he had kept closed with his entire body.
And then the blow came.
A volunteer approached Mariana with a folder.
“Are you ready for Monterrey?”
The room didn’t freeze all at once.
It froze in parts.
First Mariana.
Then Andrés.
Then Renata, who was listening carefully while pretending to play.
“What Monterrey?” the girl asked.
Mariana closed her eyes.
It was a huge offer. A national foundation wanted Mariana to direct a children's reading program in Monterrey for a year. More salary. More reach. More opportunities. Everything she had dreamed of.
The worst part was that she deserved it.
That night, Andrés talked to the twins in the living room. He didn’t lie to them. He had already learned that pretty lies also hurt.
Mateo didn’t cry.
He just opened his notebook and wrote:
“Identified threat: Monterrey.”
Below he wrote:
“Plan: none.”
Renata hugged her journal.
“If someone leaves for a good reason, does it hurt the same as if they leave for a bad one?”
Andrés had no answer.
He just hugged her.
The next day, Mariana came to the house.
The kids behaved too well. That scared her more than any tantrum.
Renata handed her an open diary.
Mariana read:
“Today Dad played Mom’s song and didn’t turn it off. I still miss her every day, but it doesn’t hurt all day because some people help carry it.”
PART 3
Mariana lifted her tear-filled eyes.
Renata whispered:
—If you leave, will it hurt all day again?
No one breathed.
Mariana knelt in front of her.
—I don’t know, my girl. And I won’t lie to you.
Renata trembled.
—But I do know something. I am not your mom. I will never take her place. Sofía will always be your mom.
Mateo pressed his lips together.
—But I love you both. And loving someone doesn’t become a lie just because life gets complicated.
Andrés had to look away.
Mariana saw it.
The children did too.
Everyone noticed.
In the library, Andrés closed the door.
—I’m not going to ask you to stay —he said.
Mariana was taken aback.
—So soon?
—If I ask you, my pain becomes a cage. And I don’t want you to wake up one day hating what you left behind for us.
Mariana cried silently.
—Sofía gave up a scholarship in Madrid when she found out she was pregnant —Andrés continued—. She said she wanted to do it. And maybe she did. But some nights I heard her crying in the bathroom. She loved us. She never regretted it. But love cost her something. I don’t want to be the man standing at a woman’s door, asking her to pay with her life for my fear.
Mariana looked at him as if she had just seen his complete soul.
—You loved her so much.
—Yes.
—Still?
—Yes.
She nodded.
Andrés took a deep breath.
—And I love you too.
Mariana stood frozen.
He didn’t move closer. He didn’t touch her. He just left the truth between them.
—I thought loving after Sofía would be a betrayal —he said—. But it doesn’t feel that way. It feels like the house has found another window.
On the other side of the door, Mateo whispered:
—Tone indicates progress.
—Shut up —Renata murmured.
Mariana traveled to Monterrey for the final interview.
She was gone for four days.
Mateo checked the weather in Monterrey, although no one asked him to. Renata drew Mariana five times and tore two sheets. Andrés played music every morning, even when it hurt.
The call came on the fourth day.
Mariana asked to speak to the children on speakerphone.
—I’ve made my decision.
No one breathed.
—I’m not going to accept the position.
Renata let out a gasp.
Mateo closed his eyes.
Andrés stood by the door.
—It’s not out of guilt —Mariana said quickly—. It’s not because I was scared. It’s because over there I realized that everything I cared about was here. At Letras de Colibrí. The question box. You. Doña Rosario scolding volunteers like it was an Olympic sport.
Renata cried with laughter.
—The foundation wants to support the center from Mexico City. There will be trips, yes. Work too. But my life is here.
Mateo opened his notebook with trembling hands.
—Confirm that you won’t leave for a year.
—I confirm.
—Confirm that you will keep coming on Saturdays.
—I confirm.
—Confirm that you will remember our names.
Mariana’s voice broke.
—Mateo Montalvo. Renata Montalvo. I couldn’t forget you even if I wanted to.
Renata cried like a child, not like someone trying to be strong for the adults.
Mateo also cried, although he later claimed it was “an involuntary reaction to the emotional climate.”
Andrés sat on the floor and embraced his children.
For the first time since Sofía’s death, the crying didn’t sound like a collapse.
It sounded like a door creaking open.
Months later, Letras de Colibrí held its first big event in a hall in the Roma neighborhood.
Andrés secretly paid for everything until Doña Rosario discovered him.
—People with money should serve for something, my son. Don’t play humble.
Mariana spoke in front of parents, children, and volunteers.
—A reading center doesn’t just hold books —she said—. It holds names. It holds questions. It holds sorrows that need to sit with someone. Sometimes, a family rescues a bag in a park, but ends up rescuing much more than that.
Renata climbed onto the small stage without telling Andrés.
—My mom’s name was Sofía —she said clearly—. She sang badly, smelled like vanilla, and made burned pancakes. I miss her every day.
Andrés felt his chest crack.
—For a long time, I thought that laughing meant forgetting her. But Mariana taught me that remembering aloud gives love a place.
Mateo joined her on stage.
—My mom also danced in the kitchen. Her technique was questionable, but enthusiastic.
The audience laughed respectfully.
—My dad has resumed partial dancing.
Andrés covered his face.
—Before, I thought being prepared meant not needing anyone —Mateo continued—. Now I believe that theory was incomplete. Sometimes being prepared means knowing who can sit with you when sadness returns.
He took his sister’s hand.
—And who remembers your name.
Applause filled the hall.
Andrés cried without hiding.
When the music began, Mariana approached and extended her hand.
—I must warn you that my rhythm has been described as partial —Andrés said.
—I’m willing to take the risk.
They danced poorly.
Carefully.
With laughter.
And for a moment, Andrés thought of Sofía not as a wound or a shadow, but as music, vanilla, and love that continued to grow in his children.
A year later, Letras de Colibrí had three locations.
Mateo no longer wore a tie every day, just on Tuesdays, for research, and on solemn occasions.
Renata filled entire notebooks with smiling faces.
And one Saturday, in Chapultepec, Andrés returned to his usual stand.
The vendor pulled out three bottles.
Andrés looked at Mariana, then at the twins running toward the grass.
—Make it four.
The vendor smiled.
Andrés carried the waters to the bench where one day everything seemed impossible.
Mariana sat beside him.
—That was 78 Saturdays —he murmured.
—What thing?
—The ones that passed without them smiling.
Mariana looked at the children.
Renata shouted from the grass:
—Dad! Mariana! Come!
Mateo added:
—Family participation is highly recommended!
Andrés took Mariana’s hand.
—And now? —she asked.
He looked at his children, at their laughter, at the life that still hurt sometimes but was no longer empty.
—Now I’ve stopped counting.
And they walked together toward the noise, toward the sun, toward that part of the story where no one replaced anyone, but everyone learned to stay.
