"Maybe I've been a small part of the democratisation of celebrity, because I've been fascinated by it, and when it started to happen to me to the very limited extent that it happens to writers in North America, I was exposed to people who had the disease of celebrity. People who had raging, raging, life-threatening celebrity, people who would be in danger if they were left alone on the street without their minders. It's a great anthropological privilege to be there."
