Count on me for bringing a "red herring" criticism into the conversation, or should I say "gossip" (no I definitely should NOT, but I did);
I think the quantitative parameter of your dinner party is flawed.
There is no way with "ten" fascinating guests at a dinner party that anyone would get even the tiniest fraction of a chance to converse with even a small sampling.
Oh, it's only hypothetical? SILLY ME!
Maybe it would be better to take one at a time, and "grill 'em" (figuratively speaking)!
Hmmm, "ten" dinner parties........I think I'm on to something!
