“Here's one of the things I learned that morning: if you cross a line and nothing happens, the line loses meaning. It's like that old riddle about a tree falling in a forest, and whether it makes a sound if there's no one around to hear it.

You keep drawing a line farther and farther away, crossing it every time. That's how people end up stepping off the edge of the earth. You'd be surprised at how easy it is to bust out of orbit, to spin out to a place where no one can touch you. To lose yourself--to get lost.

Or maybe you wouldn't be surprised. Maybe some of you already know.

To those people, I can only say: I'm sorry.”
