Lol, all that effort for nothing, thanks for the input. It all went fine, except for my friends. Her friends all were interested in me for about 5 minutes and then turned back to doing nothing really. However, i had fun with her. Unfortunately, my friend who i brought (she said i should bring someone) tried to hit on her friends (i guessed this would happen and failed), but he was in a crude mood and talked to my gf about wanking and generally made an ass of himself. Then he made us follow her friends to another bar, which they lef after a while.
I had fun, one of her friends really likes me and is really nice, the rest of them semed to be uninterested. Anyway this was just the first round as these were her school friends and not her real "best friends", Great. Ahh well, i played it cool and had fun, i just know next time to go on my own.
