I'm not usually that unkind, but this man was really bothering me. I'm middle-aged now and watching my daughter go through all this. I don't envy her--at least that part of youth.
Not really a terribly unkind retort. Look, when you around slinging pick up lines you have to be ready for replies ranging from rude to wit to witless to brutal. It was a stupid tactless question anyway.
BTW, if I told you you had a nice body, would you hold it against me? (I know, it's got wiskers.)
