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.

I haven't traditionally been a family entertainer.

Children's books are often seen as the poor relation of literature. But children are just as demanding as adult readers, if not more so. I should know. I'm a children's writer myself.

I am a huge fan of 'Doctor Who.'

I just want to be happy, have kids, enjoy my life, help others and create some good work.

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.

It can be difficult to be subtle and not cartoony in prosthetics. But when you see characters like Bubbles and Desiree from 'Little Britain' on screen, it makes all the hard work worth it. It's such fun watching those transformations.
