May be a fine line but what 15 year old girl goes to a 'party' of just her and four guys ? Who could predict the outcome of an event like that? She said she drank a beer so can she absolutely pinpoint which of the 4 came on to her if any of them did ?
I can't see myself ever doing something like that even if it really happened and especially if I couldn't prove it. I think my mother warned me or I usually was with my girlfriends when we went out, didn't call it partying then. I didn't learn about how to flirt or come on to guys until I was quite a bit older.
I had an affair once which broke up my marriage and nearly got the guy killed by my ex and other unintended consequences so I tend to avoid hurting people since then.
There are men out there I could truthfully accuse of stuff or tell their dirty secrets, girl friends, too, who deceived mem, about other people. Why would I want to hurt them and their families? I wouldn't for any amount of money or spite, always had some better alternative luckily. Some of it can be proven with dna etc. Some very hard to prove if at all.
