Ok. Here is the story. I was out with a friend. We had a couple of drinks at the bar my Other buddy owns. His girlfriend called him so we picked her up. We went back to the bar and drank a bit more. My friend (for the sake of avoiding confusion ill give letters to label the people) "N" suggest we go somewhere else. M, N's Gf, says we should meet up with her friend, Z. Z just so happens to be super fucking pretty. I have seen her a couple times before and I don't believe I have blown my chances. She has worked with my ex(who was also pretty) so I know I have at least SOME social status built up with her. We all hung out together but i could only get a couple minutes alone with her. We all went back to M and N's house (so I had the perfect opportunity to play my best game) but N wanted to go to a buddies house with just me and him. So he didn't want his gorl, M, to be there. So her and Z stayed at the house. By the time we got back they were both sleeping (my friend basically fucked me over). Anyways my friend, N, is throwing a birthday party this weekend. They're will be alchohol and beer pong and just a big party vibe. 90% of the people there will know me and they all already like me. My question is how can I isolate her at this party. We both smoke and drink. But it will probably be to cold to hangout outside for too long. Any ideas? Any tips? Even if they're not about isolating her. What kind of iois should I look for in this situation? How can I open her at a party... I mean how can I spike attraction?
