Earlier quoted context omitted.
If it makes you feel better, I was still living with my parents at 24 and had never had a girlfriend and I am now happily married with two kids. Some people are late bloomers.
But it sounds like thier son is a f'ng looser. He would've had some sense beaten into him if his parents actually cared.
edit: I haven't spoken to my father in over 20 years, and I probably never will again. What finally turned me to this point was having children of my own. I saw what he really was then, and I was determined that he would never have a part in their lives. They're adults now and are free to contact him if they won't, but they know what I've told them about him, and they choose to keep the separation.
