Eyelids are really just flesh curtains. Your eyes are always “on,” always looking; when you close them, you’re watching the thin, veined skin of your inner eyelid rather than staring out at the world. It’s not a comforting thought. In fact, if I thought about it for long enough, I’d probably want to pluck out my own eyes, to stop looking, to stop seeing all the time. The things I’ve seen cannot be unseen. The things I’ve done cannot be undone.
