Often? Not hardly. I've been married 22 years and we don't have a single friend, including those that we've had since high school, that has married somebody in their 20's, or even has dated someone that young. We don't even have any friends that are divorced much less dumping their wives for sorority girls. When we do see a couple in a restauraunt or somewhere, and the man looks old enough to be her father, my husbands first thought is that it's a "paid escort".
So tell me, does your father pant after 20 something girls? I thought not. Is your mother a middle aged woman with a chip on her shoulder that your father would be much happier without? Would he dump her for a college girl? You know he wouldn't. You should try thinking before you spew trash such as this.
You say you don't date much, you should also try it, how will you know when you've found the "right one" if you have nothing to compare it to? You're living a Harlequin novel that Mr. Right is going to come riding along on his white horse and sweep you off your feet.
It might also help you to get over that older man fantasy you're having. I understand Larry's already married. Though "I am sure" his wife is probably a middle aged woman with an unbearable chip on her shoulder. Who knows, maybe you've got a shot after all...
That comment of yours was totally uncalled for. It is sad that people like you take sincere admiration for an individual and replace it with sexual lust.
