My friend advised me to go into studying art, which at first shocked me because art was so easy. It was just something I did, like breathing or brushing my teeth. It couldn't be a job. I had a much more difficult time writing plays, making myself sit at that typewriter and finish those things.

Even though I have this solid career in picture books, I've not only been thinking about kids - because I don't think that much about children; I'm not a child educator; I'm just a former child.

I open journal, I look at the picture and I remember where I was. And I remember the time of day, the temperature of the air, what music was playing, or who was talking to me, or who was looking over my shoulder and what conversations we had and the smells of the earth and the time of year it was. It's all there for me in a way that we don't get looking at a snapshot. Most of us look back at a snapshot from ten years ago and say, where was that? We don't even remember where we were.

One of the glories of doing the book So You Want to Be President? was the shifts in tone, where I was able to be humorous and then very serious. And the impeachment page is certainly the best example of that. I didn't have to think too much about how to present this one. I got the idea right away that a good way of showing the shame of President Nixon would be to put him down in the shadows under the Lincoln Monument, with Lincoln sort of glaring down at him from an elevated, better-lit position.

By the time that book So You Want to Be President? came along, we had already had enough presidents that had shown us that presidents are human beings. So I felt I was contributing to the common knowledge there, but not revealing anything really new - sort of supporting what everybody already was suspicious of.

I don't like my parents; I never will. I didn't cry at either of their funerals. I haven't missed them for five seconds. I didn't - you know, our characters were so at odds with one another right from the beginning. But I do understand them now as human beings, with the understanding of an adult.

I feel sorry for kids nowadays, because in the majority of schools across the country, the arts have been eliminated from the curriculum. There's no art; there's no music. In some cases they've taken away the libraries. They don't do theater. And these are the things that speak to the human soul.
