Fiction has to surprise me. If a character is going around doing only what such a person would do, I get very bored. I want to know more. Or have them come to a point where they’re not what I thought they were. Or that they’re not what they thought they were. It’s probably a form of childish curiosity that keeps me going as a fiction writer. I probably want to open everybody’s bureau drawers and see what they keep in there. I’m nosy.

I find this so instructive when thinking about writing characters.
