I do keep up at night. I try not to let my mind go to extremes in the middle of the night because it would be better to turn all that stuff into dreams; it would be better if I was sleeping, because dreams become good metaphors for what's really going on inside of you.

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.

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 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.

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

Humanization and coming to understand somebody as a human being is about as good a kind of forgiveness as you can get, I think.
