By the time my husband graduated from medical school I had spent eight years paying for it. On the lawn afterward his mother took the flowers out of my hands, he pushed an envelope into them, and I opened it standing in front of eighty people.

I started at thirty-three.

I am in my second year now. I am the oldest person in my class by four years and it has been an issue exactly zero times.

The closet in that old apartment I emptied myself, on a Saturday, into the recycling, because the editions were eleven years out of date and there is nothing sacred about a superseded textbook. I kept one. It has my maiden name in the front cover in eighteen-year-old handwriting.

She said that to me on a lawn in a lilac suit with my own flowers under her arm, in front of eighty people who had all just watched their children walk across a stage, and not one of them said anything, and I have stopped being angry at the eighty because they had no idea what they were looking at.

She was wrong about the arithmetic in a way she could not have known she was wrong about.
