The knock on the door was so loud that the small sheet metal house vibrated.

Ximena remained still.

Grandma Candelaria walked slowly to the entrance.

When she opened the door, three men dressed in dark suits were standing in front of her.

They didn’t look like police officers.

They didn’t seem like neighbors either.

They had the kind of posture that men who are used to obeying orders have… and making others obey them.

One of them held up a photograph.

“Excuse me,” he said firmly. “We’re looking for this person.”

The grandmother took the photo.

He looked at her.

Then he looked at the man who was sitting on the bed inside the house.

He looked at the photo again.

—Yes —he said slowly—. It’s here.

The three men entered immediately.

When the injured man saw the photograph, his expression changed.

He put his hand to his head.

As if something inside his mind was trying to break through the darkness.

“That’s me…” he whispered.

One of the men breathed a sigh of relief.

—Mr. Alejandro Velasco.

The name was left hanging in the air.

Ximena looked at the man, confused.

—Is that your name?

The man closed his eyes.

Fragments of memory began to return.

A huge building.

Meetings.

Black cars.

An argument.

A collision.

Then… darkness.

—Yes —he finally murmured—. Alejandro Velasco.

The man in the suit spoke respectfully.

—Sir, we have been looking for you for three days.

—His family is desperate.

—The police too.

Ximena looked at the man with wide eyes.

—Is it important?

The man in the suit hesitated.

Then he replied:

—He is one of the richest businessmen in the country.

Silence filled the room.

But Grandma Candelaria just crossed her arms.

“There was a wounded man here,” he said. “Nothing more.”

Alejandro looked at Ximena.

The little girl who had taken it out of a garbage dump.

That she had shared her last water with him.

That he had helped him walk when he didn’t even know who he was.

“She saved me,” he said.

One of the men pulled out a wallet full of money.

—We can reward them.

The grandmother shook her head.

-No.

Ximena also denied it.

—We didn’t do it for money.

Alejandro felt something strange in his chest.

Something I hadn’t felt for many years.

I respect.

Gratitude.

Perhaps even shame.

He looked around.

The small house.

The walls are made of sheet metal.

The old table.

And he remembered where they had found him.

At the dump.

A place where people like Ximena survived every day.

When she left the house with the men in suits, she paused before getting into the car.

—Ximena.

She looked up.

-Yeah.

—What do you want to be when you grow up?

The girl thought for a moment.

-Doctor.

—So that my grandmother can breathe better.

Alejandro smiled.

—Then we’ll have to make sure you study.

The grandmother frowned.

—We don’t need charity.

Alejandro shook his head gently.

—It’s not charity.

He looked at Ximena.

—It’s a debt.

Months later, something incredible happened.

Ximena started going to a new school.

Her grandmother received medical treatment.

And the Bordo de Xochiaca landfill received an unexpected investment.

A recycling center.

With secure employment for many families.

One day, while they were walking through the new building, Alejandro said to Ximena:

—The world thinks I changed your life.

The girl looked at him curiously.

-And not?

Alejandro shook his head with a calm smile.

-No.

He paused.

—You reminded me who I was meant to be.
