I remind him that he's part of my mind, so I can answer the question on his behalf. He challenges me to do so. I become angry. I decide that in future dreams, I'll be giving my characters much less independence.

The list of good chapters goes on and on. Strangely enough, Wiley Publishing hasn't yet approved the project.
