I used to teach on a college level, and I've taught in schools where kids just wanted to be artists, and I used to be furious with them if they didn't read, because they just seemed so - their education seemed so thin if all they could do was pick up a paint-loaded brush and fling it at a canvas. I mean, there was nothing to express there, except maybe their own personal feelings. But if they're not - if they don't have a grounding in the way these things have been expressed by other people down through the centuries, then they're lost.

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.

The odd thing about recurring dreams is that, no matter how many times you dream the same thing, it always takes you by surprise.

What I try to do in my picture books is to be all-inclusive, but not exclusive, to not exclude the kid and not exclude the parents from the experience. And it's not a very easy task; you can't find stories that work that way too much of the time.

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.

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 think drawing is really the basis of all art, even sculpture, film. The greatest filmmakers have always been able to at least roughly sketch out their ideas in storyboards. And black and white in particular is a good place to start.
