"When I'm not writing books I like to draw and to make things out of wood. I also like to play the piano. I'd like to play it well, but I can't, so the rest of the family has to put up with my playing it badly."
As a passionate believer in the democracy of reading, I don't think it's the task of the author of a book to tell the reader what it means.
The meaning of a story emerges in the meeting between the words on the page and the thoughts in the reader's mind. So when people ask me what I meant by this story, or what was the message I was trying to convey in that one, I have to explain that I'm not going to explain.
Anyway, I'm not in the message business; I'm in the “Once upon a time” business.
