The stories my pupils told me were astonishing. One told how he had witnessed his cousin being shot in the back five times; another how his parents had died of AIDS. Another said that he'd probably been to more funerals than parties in his young life. For me - someone who had had an idyllic, happy childhood - this was staggering.

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
