So that's ten years before she was born. Ten years before I was born (1965) would have been early rock 'n' roll (which I love, FWIW). Now at age 25, I might have referred to Rock Around the Clock or Maybelline as an oldie, but I wouldn't have thought of them as really old. Something by Al Jolson or Bessie Smith? Different story.
It could have been much worse. She could have stayed silent about it because she didn't think you looked good regardless of age.Then to make matters worse she pulled this.
I lost 25 pounds. I am feeling pretty good about it. She says
"Yea I notice the difference. You look really good." She could have left it there and I would have been happy. A cute girl half my age calling me good looking. But she adds 5 words that killed it. "For a man your age."
UGH!
