It is a complete and total lie. A fiction. You're giving credibility to something that didn't even happen.
I’m not sure it’s a outright lie...as a high schooler I went to plenty of parties that got a bit out of control with kids hooking up to make out, maybe an attempt to get to first base in a backroom...
After several 36 oz beer steins, and some huge bong hits, a few times I found myself making out with a complete stranger (girl)
The music was always loud and at least for the kids I hung out with pot and booze was plentiful...
As for the words “force himself on her” was it a kiss, A attempted rape, to cop a feel or grab her butt?
It might have happened to this girl but was it even Kavanagh? 35 years is a long time ago...to remember...
