I don't necessarily think stories have functions any more than diamonds have functions, or the sky has a function... Stories exist. They keep us sane, I think. We tell each other stories, we believe stories. I love watching the slow rise of the urban legend. They're the stories that we use to explain ourselves to ourselves.
Neil Gaiman"Only write what you know" is very good advice. I do my best to stick to it. I wrote about gods and dreams and America because I knew about them. And I wrote about what it's like to wander into Faerie because I knew about that. I wrote about living underneath London because I knew about that too. And I put people into the stories because I knew them: the ones with pumpkins for heads, and the serial killers with eyes for teeth, and the little chocolate people filled with raspberry cream and the rest of them.
Neil GaimanThere are stories you build and there are stories you construct; then there are the stories that you hack out of rock removing all the things that are not the story.
Neil GaimanThe ideas aren't that important. Really they aren't. Everyone's got an idea for a book, a movie, a story, a TV series.
