Yes, 17 is young and you don't know anything about my daughters you pervert, so STFU
If your daughters are normal teenage girls, they’ve done most of the things YOU did in high school and maybe even a few you didn’t know about. You know, making out and petting, maybe even more. Possibly more. Probably more.
That’s if they are normal.
But maybe they are, as you insist, abnormal.
Get your head out of the sand.
I think he was making a generic statement about kids today... do you use language like STFU in front of your family?
