how can anyone man/woman/other gender not recall at least the year they were raped?
It's more than that.
According to the bad actress, she claimed she didn't know where she was. She claimed she ran from the bedroom, past her supposed attackers, and went outside. She also claimed she didn't know who took her home.
I'm only a few years older than her, and I can tell you no teenager back then had a cell phone. So in order for her to get a ride, she had to go somewhere and had to call somebody: a neighbor, a gas station, a convenient store. Then after she called this person she didn't remember, she had to tell them where she was at.
So what her claim is that she couldn't' remember who she called, where she called from, or how the person called was able to find her.
Yeah, who couldn't believe that?
