I have watched part of it and then I lost the remote control for the dvd player. I'm reading a book which talks a lot about switching and internal conversations. It's called First Person Plural. It's very witty. I haven't laughed so much for quite a while. So I recommend it.

This book probably stimulated some of the thoughts I put in my post above.

I'm going to post some quotes from it soon.
