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.

I began drawing probably when I was - around the same time everybody else puts a mark on a piece of paper with a crayon - when I was two, probably. The difference between me and everybody else is, I kept doing it for the rest of my life; there was something very satisfying about that.

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'm a reader. I like - I'm a great reader. I keep going back, though, to certain authors, just like I love film, but I keep going back to just five or six certain filmmakers. In literature I like Chekhov, for example; I think he's my favorite. And Flaubert - you know, that kind of concision. But I also like Tolstoy; I love those romances that, you know, weigh 500 pounds and take months and months and months to read.

My interest really is psychology, what's going on in people's minds as revealed on their faces and in their posture. That is my strength. And it's something that came from probably being a silent observer for most of my life and having to read what was going on in people's minds from only their postures or from their expressions.

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.

I grew up going to the theater. That was one of the nice things my mom did was she took us to plays and symphony concerts and to the museums. Theater captured my imagination. I just loved the idea of that box, which is essentially what a stage is from a certain distance, a box with all this life going on in it. So, I was eleven when I wrote my first play. Of course, it was horrible.
