@ossobuco,
Yeah, but here in MA, that is what people do: hold doors for each other. Men, women, children . . . everyone holds doors for everyone else.
I just think it would be nice to have dinner with a man who doesn't sip my wine, screw up his face and say, "Yuck." Or a man who comes home with a bottle of California jug chablis because I tell him I like whites from Burgundy.
On the other hand, one definition of sophistication is common sense. When you think about it, common sense does make a nice synonym for sophistication because sophistication implies knowing how things work.
