I had a very happy childhood, but I wasn't that happy a child. I liked being alone and creating characters and voices. I think that's when your creativity is developed, when you're young. I liked the world of the imagination because it was an easy place to go to.

Writing for radio really focuses the mind, because you can't rely on thinking "Oh, just pull a funny face at the end of this sketch." You've got to try to work on the words.

People think writing a children's book is something you could do in an afternoon but it's actually really hard.
