The porch step was fixed on a Tuesday morning. I know it was Tuesday because I remember thinking I had to get to the grocery store before the mid-week rush. The tread had been cracked for weeks and I had been meaning to call a handyman, but then it was just fixed.

New wood, perfectly sanded and sealed. I hadn’t called anyone. I hadn’t paid anyone. It was just done.

I didn’t think much of it at first. Maybe I had forgotten calling someone, or maybe one of the neighbor boys had decided to be helpful. My husband Walter had passed away a year before that, and people in the neighborhood were always being kind. I figured it was just one of those things.

Two months later, the gutter brackets were replaced. Then the railing. Then the porch screen. It was always the same. I would go to sleep in a house that felt tired and worn, and I would wake up to find it a little bit newer. Eight years of small repairs, always done overnight, always while I was sleeping. I have never seen a truck. I have never heard a hammer.

I tried to catch whoever it was. I set up a camera once in the hallway pointed toward the front door. I checked the tape the next morning, but the battery had died just before midnight. The screen was just a static-filled gray. I felt like a fool, sitting there in my kitchen with a cup of coffee, looking at nothing.

I guess I just stopped asking questions after a while. It was easier that way. When you are a widow living alone, you start to appreciate the little things. I told myself it didn’t matter who was doing it as long as they weren’t hurting me. I was safe.

The house was being taken care of. What more could I ask for?

Last spring, I found a small notebook tucked under the welcome mat. It wasn’t mine. It certainly wasn’t Walter’s. It was a spiral-bound thing, the kind you buy at a drugstore for a dollar. I opened it up, and my heart started thumping against my ribs. It was a list. Dates on the left, repairs on the right.

Every fix I had noticed was there. The porch step. The gutters. The railing. There were things I hadn’t even noticed, like the loose shingle on the roof and the kitchen cabinet hinge that used to stick. It was all written out in a very neat, very careful hand. I sat on my porch and read every single page.

The last page was not a list. It was addressed to me. The handwriting was shaky, different from the list itself, like someone trying very hard to hold a pen steady. It said, I am doing this so you remember how we built it together. I am doing this because you are still mine.
