If, for some reason, I cannot bear to work on something that needs to get done, I'm not going to force that. I'll just take a mental vacation. I think the best solution sometimes to working out a problem is to walk squarely away from it.

There are just certain things you can't talk about with kids. I just totally do not believe in this sort of Bart Simpson character who infects so much of our literature and film and TV stuff nowadays, these know-it-all kids who seem to understand the hypocrisy of the adult world so thoroughly and can talk about it with such articulateness. That's bunk. Kids are kids; they're innocents, they really are. For a long time, no matter what they see, no matter what they're exposed to, they can't get it until they have developed enough.

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.

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.

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.

Leaders of the world, my message to you is simple: to achieve universal peace and understanding on this planet you have only to speak plainly, even though you may look foolish. This is a thousand times better than looking good and talking nonsense.

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.
