My son has a pet crayfish. Which, I suppose, is another way of saying that I have a pet crayfish. This isn't something I was expecting to ever say. But then, my experience of parenthood can more or less be summed up by the fact that I have an actual list of "Things I Never Thought I'd Say."

Red—that is the crayfish's name, and also its color, more or less—came to live with us in May, having previously been part of my son's third-grade unit on life science. He (my son assures me that Red is male) spends most of his time lying around on his side, a disconcerting habit in an animal that lacks eyelids, making it look like he is constantly dying or already dead. When I see him doing that, I tap on the side of his aquarium, my finger making a dull, ringing thump on the plastic, and Red immediately rights himself and either brandishes his tiny pincers at me or scurries into the little flowerpot we've provided him for "privacy." These are Red's three general states of being: depressive malaise, ridiculous bravado, and hiding in darkness. Which, when I put it that way actually makes the smelly little creature kind of relatable.

When I was a kid, a few years younger than my son is now, we lived in a cabin in Bixby Canyon, maybe a mile or so in along the canyon floor from where the creek ran under the famous bridge that causes so many traffic problems now, lines of parked cars a quarter mile in each direction as the tourists jockey for a spot to take the same exact photograph as the people they're elbowing out of the way, hundreds of them every day. There weren't so many of them back then, but either way we had our own little bridge as well, though ours was just a little wooden foot bridge and not a historic concrete arch. The creek ran through our front yard, and in the shadows cast by that little foot bridge, under the rocks, there were rainbow trout and crayfish, though we called them crawdads. We would pass the time, sometimes, by tearing up slices of American cheese, rolling the bits into balls and dropping them over the side of the bridge to feed the trout and the crawdads. The first time I saw my mother's boyfriend doing that, I thought he was throwing pebbles at them. I tossed in a big rock, which made a satisfying splash before it crushed one of the crawdads. I got a spanking for that.

We lived in that cabin about a year, from one winter to the next. I learned a lot of things that year. I learned which spots in the creek the crawdads liked to lurk in, and how if I dipped a blade of long grass in front of them, they'd grab it and wouldn't let go even after I pulled them out of the water. I learned what crawdads taste like when my mother's boyfriend decided to take us to a different part of the creek and showed us how to catch a whole bucketful, how they turn bright red when you boil them, how to tear the tails off and suck the meat out. I learned that sometimes my mom's boyfriend would be interested and affectionate with us, and sometimes he would be sullen or angry, but I never quite learned what would make the difference, or how to anticipate his moods. I eventually learned that I wasn't responsible for his moods, but not that year.

I asked my son the other day if he loved Red. He thought about it for a second, then cocked his head and said "No, but I'll still be sad when he dies." It seems like this is our main interaction with Red apart from feeding him and changing his water once a week—that is, waiting for him to die. Crayfish can live several years according to what we looked up online, but what we heard from teachers and other kids' parents was that they usually only last a few weeks after the kids take them home, and, indeed, Red has already outlived the rest of his third-grade science class cohort. It seems a little strange to me, sometimes, that the boy is so attached to this creature that gives so little back, but this is what he's like. He cares. I think sometimes that he's better than I am, and that's a good feeling.
