Folks around here drove for a hundred miles to get Krispy Kreme donuts. Then they built a Krispy Kreme donut place in town, complete with drive-through. The place was closed within 6 months. Guess the novelty wore off.
Like the phrase goes, "When you see a bandwagon, it's too late."

How is (most) of this advice "antiquated theories and nonsense" as the writer so snarkily puts it? Yes, it's a product of its times but I see more manners and common sense being pitched here than anything that would be "demeaning" (however your interpretation) to women. Lemme see: Don't pick at your clothes like a kid, don't yammer nonstop, don't start talking during a dance, don't drink too much, focus the conversation on the other person. Sounds like good advice to me.
