You've heard enough of both kinds to know the difference instantly - the sound built for someone watching, and the sound that wasn't built for anyone at all. What's in here is the second one; I wasn't thinking about a camera, and I definitely wasn't thinking about you. That's what you can't close the tab on, isn't it - the fact that it had nothing to do with you, and your body responded anyway. You already know you'll be back. What you came here with doesn't go away on its own.
