I heard a white writer say, 'Oh, I'd never put black people in my writing, I'm afraid I would offend someone by doing it wrong.' I can't bear that!
There is a lot of censorship about writing that's exerted from all directions, from families or governments and society, even the fear of being offensive in some way.
When I've taught writing to five, six, and seven year olds, it's not very different than talking to an adult writer. They're writers then, and when they get to be young teenagers they're not anymore. You might go and talk to them about writing, and they'll be very self-conscious or will have detached themselves from the group.
