Autumn Kent is a mathematician at the University of Wisconsin-Madison, and I am lucky enough to call her a friend. Last fall, I was one of the people who was surprised when she came out as a trans woman. I don’t know many trans people, or at least I don’t know that I know them, and I’m grateful that she and my other trans friends have helped me become more conscious of issues affecting trans people and challenged me to be a better ally to trans people.
