You’re giving her too much credence. I don’t believe Kavanaugh ever did such a thing.
He probably didn’t even know her. I agree with you. Just saying the whole deal is ridiculous. Some dude jumping up and down on another guy while another guy was on her... it’s all nutty. If it did happen with another guy, it sounds more like playful hi-jinks that after 30 years she morphed into something else entirely.
