I just happened to have my camera and be photographing my friends. It was totally innocent; there was no purpose to the photographs. There was a purity to them that wasn't planned; it was realism. Over the years, the work has changed for me. I know that I have wanted to repeat myself, but I can't. I've been lost a lot of times, but then I'd just get an idea and photograph it. Once I'd started, I'd know exactly what would go down and how it would end. So I just quit doing it, because it loses all interest for me when you know what's going to happen.
