Novels are like marriages. You have to get into the mood to write them — not because of what writing them is going to be like, but because it’s so sad to end them. When I finished my first book, I really felt like I’d fallen in love with my main character and that she’d died. You have to understand, writing a novel gets very weird and invisible-friend-from-childhood-ish, then you kill that thing, which was never really alive except in your imagination, and you’re supposed to go buy groceries and talk to people at parties and stuff. Characters in stories are different. They come alive in the corners of your eyes. You don’t have to live with them.
