“I love the fact that little kids think I'm a witch. A mum might come over and say 'I'm sorry to disturb you, but my daughter thinks you're in 'Harry Potter.' I'll say 'That's cool' and take the kid aside and say, 'I'm a witch. If you don't listen to your mum, I'm going to haunt you!' It's brilliant. I can scare kids into doing their homework.”
