So we [with Kate DiCamillo] would act them out, we would toss ideas back and forth, we would laugh, we would argue. Sometimes it went really well, sometimes it was such a pain in the ass. Our other rule was that we wouldn't work on it at all when we weren't in the other's presence. It was really hard not to do that. We'd start going on email back and forth, 'What do you think about this, what do you think about that?' But, no, no, no, it had to be live. So we forced ourselves not to look at it except during those two-hour stretches when we were actually with each other.
