The first things I remember drawing were battles - big sheets of paper covered in terrible scenes of carnage - though when you looked closely, there were little jokes and speech bubbles and odd things going on in the background.
Worrying can be a kind of caring, and as such is a healthy part of a balanced emotional life.
I had just been promoted to the first rugby team. It was a perfect, wonderful coming of age. My brother was already in the team, and my father had come to watch us. We went home, and my father died in front of me. Horribly, in about half an hour. He had a heart attack.
Writers are articulate. Artists find it more difficult.
After art college, I got a job as a medical illustrator, and I was pretty good. I had to imagine what was going on in the operations because the photographs just showed a mess.
My dad never decided what he wanted to do; at times he fought in the army, was a teacher, a boxer, a light engineer, and a then a publican. My mum was a traditional housewife and mother. They showed my brother and I unconditional love.
I see 'Hansel and Gretel' as a breakthrough book for me, and one of the reasons is because I started to apply meaning to the hidden details.
Having a memoir and a retrospective of your work running almost simultaneously when you're still alive does feel a bit posthumous.
I don't like narrowing my readers down - there's not a particular age or gender or nationality. I suppose I'm aiming at the child I was.
Children will come out and listen to a writer whose books they like. They don't need a government agency or a medal that says 'laureate' to continue that.
As adults, we've seen so much before that we often turn the pages of a picture book without really looking. Young children tend to look more carefully.
