Not sure I'm entirely happy with your classification system, Daddima

If all of those you choose are to be at the same dinner party, would they be compatable? You would have to select them carefully, or some or all would try to hog the limelight and upstage the others. If all are talkers and none listeners, you could end up with pandemonium.

Sandi T is gay so which guest list should she be on Daddima? She’s very bright and very funny, a welcome addition to any dinner party I would think. I remember her making piles of sandwiches on Number 73 (is that what it was called?) years ago.
