It could be she was ashamed of being an exotic dancer. While the money is very good, and she can make her way without working really long hours, it's a job that many parents would (rightfully so) frown upon. If she talked about the attack, she would also have to let her parents know about the dancing.
Someone very dear to me was the victim of date rape at age 17. Her parents, who are super-protective, did everything right: they called the home where the party was being held and spoke to the parents, dropped her off and picked her up, met the young man and spoke to him, etc., etc. He still dropped a mickey in her drink and raped her.
It took her 6 weeks to tell her parents what happened, when she became suicidal.
Don't judge based on that; rape impacts everyone differently.
I just don't understand how he could not know what her job was. Did he not ask her where she worked?
after reading about her real job (a prostitute) and the duke students' police records, i am getting the impression that two prostitutes were hired for a drunken party that got very out of control.
imagine two prostitutes in a house with a whole bunch of drunken lacrosse players, one third of whom have been arrested previously.
anything could have happened there.
