In fiction the narrator is a performance of voice, and it can be any style of voice, but I'm interested in the ways that a voice that knows it's telling a story is actually telling a different story than it intends to. In the way that I can sit here and tell you what I had for breakfast, but I'm really telling you that I'm having an affair, something like that. And I don't think my writing is plain, but I think a lot of my characters are just talking. There is vulnerability there, in that we can start to see through them, we can start to see where they're deceiving themselves.
You know that's why people don't like unlikeable characters. It's not that they're not interesting. Everybody knows the most interesting character in a book or a movie or whatever narrative is the villain.
I don't really pity any of my characters. I hold my characters under a harsh fluorescent lamp and ask "Who are you?" I'm not doing their makeup or giving them hairdos. They present themselves to me as they are and then I let them say what they want. Usually they're saying something too honest.
Building a relationship with the character. It's just like sitting with someone you know. It's very easy to predict when they're going to shake their head or say whatever, but because I'm the author I have to make characters do what I want them to do.
