The next day, I brought cookies and a small envelope to the neighborhood where I’d seen him walking. A kind woman opened the door. “That’s my grandson, Mateo.”

I gave Mateo the cookies and $50. His grandmother teared up. “He’s saving for a new computer for school.”

I smiled. “I might be able to help more.” My late husband had been a professor. I made a few calls.

A week later, Mateo had a new laptop and a grant.

He gave me groceries. I gave him a future.

But truly, I was the one most blessed.
