I sometimes envy people who have a family home to return to, a place where they grew up, where their parents or even their grandparents lived.The closest thing I have is the farmhouse where my mother grew up. My grandparents lived there until they died, and my mother’s older brother, Andy, and his wife, Bea, live there still, despite everyone’s insistence that, at 90, Andy might want to think about moving to a place with fewer stairs, a little bit closer to town.“I’ve lived here almost all my life!” Andy says. “Why should I move now?”People could say, “Well, because you’re 90 years old, and you broke your leg a year ago and it’s a big old house for a couple of people who are no longer young.”But most people don’t bother to say that because it wouldn’t change Andy’s mind.

They didn’t know what to do. My mother was the oldest of the three, and they sat together on a roll of linoleum until someone came and brought them to the new farmhouse. That was a very long time ago, and my uncle Andy has been there ever since.The home I grew up in was sold long ago. When I married Peter, I sold my house, and we lived together in his home. We sold Peter’s place when we moved to the city. Then we started coming to Mexico. Last night, I realized my idea of home was, once again, changing.This little apartment that we do not own—where we have no more than two matching plates and bowls—this place ...
