JAMES LILEKS:

This is why I don’t believe in ghosts: if they existed, they wouldn’t float down the hallway weeping or make the walls drip with blood – they’d wake you up, whisper “come here” and bore you with a story about how little Jimmy used to sit in front of the window, here, and wait for the mailman when he sent away his boxtops for something. That’s the stuff ghosts would want you to know about.

I think he’s right.
