" It's hard to remember someone when you don't know what they look like. Because A changes from day to day, it's impossible to choose a memory and have it mean more than that single day. No matter how I picture A, it's not going to be what A looks like now. I remember A as a boy and as a girl, as tall and short, skin and hair all different colors. A blur. But the blur takes the shape of how A made me feel, and that may be the most accurate shape of all. "
