My opinion is that if, by a certain age, someone hasn't learned what is and isn't acceptable and expected in a dating environment, they will never learn.
CASE: a friend of mine has been dating this guy for a few weeks. Personally, I'd have put him on the road after the first one, but she likes him for some reason. He insulted her at dinner, making fun of what she wore. Then he drank too much. Then he...yes, he did...he burped out loud at the table. At least he didn't fart, so that's something.
Subsequent dates have been more of the same.
Anyway, she and I were having this conversation last night and she says that it's possible that no one has ever told him that that's not how we act. She thinks that having a conversation with him about why these actions offend her might make him see the light.
I told her that he's a lost cause. If he doesn't know these things by his age (which is early 40's) he has no interest in learning.
What say you? Can you teach an old dog new tricks, or should you just have them put down? (She's cute, too, so no need to desperately cling to some loser for fear no one else will ever ask her to dance.)
