Ideas for books come in many ways. Most of them are just sudden insights. I remember when I wrote Brown Bear, I was riding on a train. I heard, “Brown bear, brown bear, what do you see?” And I grabbed my pen. I didn’t have anything to write on, but I did have a newspaper. I folded the newspaper and wrote crosswise, “Brown bear, brown bear, what do you see?” I thought for a minute, and I either heard or imagined, “I see a red bird looking at me. Red bird, red bird, what do you see? I see a yellow duck looking at me.” The pattern is there. The book was broken. All I had to do was write it out. It was finished in 15 minutes.
