“If you just warn people, they often simply ignore you. But if you ask them a question, then they have to think about it. And once they start to think about the consequences, they almost always calm down. Unless they're drunk, of course. Or stoned. Or aged between fourteen and twenty-one. Or Glaswegian.”

“Once you start thinking about the lies people tell when they don't know they're telling them, the truths people reveal when they think they're lying, then you can start to build a world.”

“Why do we always begin to think about people when they die? I think we should think about people while they're still alive! That way, they can know that we're thinking about them! I always tell people when I'm thinking about them, or that I thought about them, or that I have been thinking about them and it almost always scares them away, but so what, I am practicing the art of life and if that is frightening to them then maybe they need to start living while they're still alive!”

“No one is thinking about you. They're thinking about themselves, just like you.”

“Some people spend their entire lives thinking about one particular famous person. They pick one person who's famous, and they dwell on him or her. They devote almost their entire consciousness to thinking about this person they've never even met, or maybe met once. If you ask any famous person about the kind of mail they get, you'll find that almost every one of them has at least one person who's obsessed with them and writes constantly. It feels so strange to think that someone is spending their whole time thinking about you.”

“Having an answer is a comfort. It's when you start asking questions and those questions pull threads in the larger fabric, you're forced to wonder what you're left with. And for people of any age, it's scary to think the fabric of the universe - or the universe as you've always believed it existed - can just unwind, you know?”
