I think my first experience of art, or the joy in making art, was playing the horn at some high-school dance or bar mitzvah or wedding, looking at a roomful of people moving their bodies around in time to what I was doing. There was a piano player, a bass player, a drummer, and my breath making the melody.

If there's a photo of a roomful of kids I'm the one with the biggest smile or my hand over my face.

All along - not only since she left, but for a decade before - I had been imagining her without listening, without knowing that she made as a poor a window as I did. And so I could not imagine her as a person who could feel fear, who could feel isolated in a roomful of people, who could be shy about her record collection because it was too personal to share. Someone who might have read travel books to escape having to live in the town that so many people escape to. Someone who - because no one thought she was a person - had no one to really talk to.

I'm a spoilt brat. I thought I was just going to walk in and make movies. But I'd been my own boss for so long that all of a sudden to be facing a roomful of people who were niggling over every little scene... I just thought I'd go back and draw my comics and have a happy life.

When you see a struggle that you may be having personally put on a big screen and in a roomful of people then it makes you feel less crazy or alone because you're seeing that other people are dealing with it too. You get to see in this imaginary scenario how people might try and answer some questions or deal with some problems.
