Girls are complicated. The instruction manual that comes with girls is 800 pages, with chapters 14, 19, 26 and 32 missing, and it's badly translated, hard to figure out.

I think pain is a very - it's an extremely hard thing to empathize moment to moment.

I would cling to unhappiness because it was a known, familiar state. When I was happier, it was because I knew I was on my way back to misery. I've never been convinced that happiness is the object of the game. I'm wary of happiness.

I do have a huge problem, a huge problem. In fact, worse than watching is hearing. I cannot stand to hear my own voice. When it's coming out of my mouth right now it sounds fantastically interesting to me. It's rich in light and shade, it goes up and down. But when I hear it either on TV or even on someone's answering machine, I just sound like I've had half my brain removed.
