Robert had a sixth-grade education. He was not a reader. He kept maybe four books in the house his whole life and I don’t think he finished any of them. He was not a man who talked about learning or self-improvement or any of that.

He was a man who fixed things when they broke and showed up when he said he would and didn’t ask for credit for any of it.

And he had spent twenty-two years teaching a little boy in Guatemala to read, through handwritten letters, thirty-eight dollars at a time.

I went looking after that. I found the account. It was an old savings account at a credit union across town, one I’d never had any reason to open. There wasn’t much left in it. He’d been drawing it down to keep the payments going even after he retired. The last transfer was dated eleven days before he died.

He never missed a payment. Carmen said that twice, and I’ve thought about it probably a thousand times since.

I don’t know why he didn’t tell me. I’ve asked myself that so many times. Maybe he thought I’d think it was frivolous. Maybe he just wanted one thing that was entirely his own. Maybe he was embarrassed, which sounds crazy, but Robert was like that. He didn’t like being seen doing good things. It made him uncomfortable. I used to tease him about it.

The letters finally came in the mail about two weeks after I talked to Carmen. She sent the full packet, both sides of the correspondence, bound in chronological order. 264 letters. The stack was about three inches thick.

I’ve read all of Mateo’s. I haven’t been able to read Robert’s yet.

Mateo’s last letter was dated four years ago, when he was 23.

He wrote in English, careful and deliberate, and he thanked Robert for being the first person who ever wrote to him like he mattered. He said, “You never made me feel small.” He said he had a daughter now, and that he was teaching her to read the same way Robert taught him.

I’m sitting here with that letter on my lap right now.

Thirty-one years. I knew the man’s coffee order and his shoe size and the exact way he’d sigh when he was tired. And he had this whole quiet piece of his life that I never touched, this little boy he’d been writing to since 1999, and I didn’t know. I just didn’t know.

I keep thinking I should feel cheated out of something. But the more I read Mateo’s letters, the more I think maybe Robert just knew himself better than most people do. He knew he’d never brag about it. He knew if I knew, it would become a thing, a family thing, a story we told at dinner. And he didn’t want that.

He just wanted Mateo to learn to read.
