So here's the complete, raw transcript of today's session.  I simply
shut my lap top mid session, and flipped it up when I got back to my
office -- unusual to have this work so smoothly in Windows, although I
know iPeople take this stuff for granted.

Replying to Andre's question, yes, same group.  And notice how my
objects start eating each other at the end, and yet I'm able to still
feed the dog a big juicey steak, even though it's a list item in the
monkey's stomach (where our monkey is in the human's).

Oh, and at one point I create a 100 monkeys.  Arthur probably thinks
I'm making a political statement or something.
