I’m very lucky to write for children, because I don’t have to deal with popular culture. I can just deal with core fundamental issues: jealousy, love, hatred, sadness, joy, wanting to drive a bus. The fundamental core emotional things. And just asking questions like, ‘How do you know when you’re in control? What is a friend? What are relationships between people?’ These are all things that I haven’t figured out yet. I’m very lucky in that I don’t understand the world yet. If I understood the world, it would be harder for me to write these books.
