It sounds purely psychological anyone you meet in a club you may well never see again, if its people at work or school you will see them again. I could get all Mystery and talk about cavemen but basically your mind says if I fuck up they will remember it everyday and tell everyone etc. This won't really happen but remember the old saying about your own doorstep.
If you are gaming on campus I would stick to people not in your classes or if you want to game in your classes then go under the radar and build attraction so they make the first move. Hope that helps
