There is this humor that can be appreciated on an adult level. It’s an interesting combination, and it’s not something that you plan. It’s just the way it happens. Somebody asked me once, “Well, do you actually illustrate for adults, so that adults will like your illustrations, too?”
And I said, “No, I don’t. I illustrate for myself.” What pleases me is what goes into the book. And if it appeals to adults, too, that’s great. I know it appeals to kids. And I know that because of the kid in me, because I don’t think I ever really grew up, anyway. I still peer at things the same way children do, and give things a lot more attention than adults do. And I think that goes into my illustrations, my thinking, and my stories.
