Before I'd written movies, I never could do big set-piece scenes with a lot of different speakers - when you've got twelve people around a dinner table talking at cross purposes. I had always been impressed by other people's ability to do that.
But when I lose my temper, I find it difficult to forgive myself. I feel I've failed. I can be calm in a crisis, in the face of death or things that hurt badly. I don't get hysterical, which may be masochistic of me.
