“The one good thing about pain is that while you can remember it, you can't recreate it; you can't truly think it into recurring. You can rate it in retrospect—a toothache vs. banging your funny bone—but it doesn't work the way words or music do. You can hear things in your head, voices, music, over and over. You can close your eyes and visualize a place. But pain, the experience of it, either is or isn't. You are in pain, or you aren’t.”
