When i go out i occasionally see girls that look quite hot (Appearance) but they also look really cold (behaviour). What i mean with that is for example in a night enviroment there are girls standing in the middle of other people that all have fun. But they just stand there and maximum smile but overall look really cold. Don't get me wrong its easy to hook up girls that are aswell having a fun time but i can't figure out how to hook cold girls. And i even think that it isn't even related to their mood. I feel like its more about being too shy or something else?!? Any experiences or tips?
