Sometimes I'll be confident and go into a shop and say, "Hello, yeah, all right," and then the next day, if someone looks at me or talks to me, I just don't know what to do. If you're walking down the street with a baseball cap, you might be fine. But if you're in a pub and you see someone look at you, you think the worst thing in the world now is if they come over. It's a really weird feeling.
