So I would agree to the posts before that you pushed too fast, if you could not isolate her you could at least have tried to win over the whole group and not only that one girl.
Oki so you know how screwed it is, the bottom point is as I said they were sort of double dating. I couldn´t not win over a double date, no mater how much social proof you can present you cant get someones pointed girl and rely on social proof. I fight against the idiom, against the place and so on. I only get upset cause the dude pulled her like she was a dog, and after, the AFC simply dumped her. And she says me hey go away. This is fucking dumb, I like my teeth and I don´t wanna enter into a dumb discussion with drunk people (you know how this losers drink) for a girl I barely know into a city Im leaving in 2 weeks. Point is she was with the hands inside my shirt, and rubbing against me, you know from your knee to your neck once she stopped in from of me and smiled I got the perfect shot for the kiss sorry couldn´t ignore that. Still I think it is also much more about this retarded people from small cities.
About the isolation... Kinda hard, no corners and so on :p You don´t have a place where other people are kissing and so on germany is screwed up bros.
