I'm very interested in the way people interact emotionally.
When you have people who get angry quickly, you have to learn the rules to avoid being in that situation.
You write the facts as you see them, and there isn't a lull with a lot of description. No wonder people like to write about murder mysteries and dead bodies!
I love reading fiction about people who are connecting intellectually. I find that exhilarating.
I'm always interested in a claustrophobic situation where people might be powerless to do things.
