Anyone who has problems, or worries, anyone who laughs and cries, anyone who feels can write. It's only talking on paper... talking about the things that matter to us.

What inspired me to become an author? I think it was the snow in New York. I looked out the window and I said, 'Well, I have to get dressed every morning to go to teach, but if I write a book, I can stay home in my bathrobe, eat candy corn.'

Sometimes when I visit schools, kids will interview me for the school newspaper. They ask me questions and my answers tend to go on and on, and they try to write down everything I'm saying as quickly as they can. And one day, a kid holds up her hand and said, 'Do you think you could just answer 'yes' or 'no?' Aren't kids wonderful?

I myself was terrified during the Second World War. The war started when I was six, and I was so sure that we were going to be bombed and killed. My imagination is my biggest plus and my worst minus.

What I think of sometimes, as I read the new books - do kids really need to see such a seamy side of life? I'm in the minority, such an old woman, perhaps. I love the books that have given kids joy, that give them hope at the end. Sometimes it seems to me the books right now are very depressive.

Revision is the heart of writing. Every page I do is done over seven or eight times.

Outside of family, writing is essential. To me, it's like breathing.
