lots of things :) imagine a night out, going to a club, finding out its full of girls, it would be a pretty shyte night out that would be , no body to come and try to chat you up, no one you can tell to pish off.. you would be lost, wondering what to complain about, plus there will be a massive queue at the bar, as when a girl has to go and get a drink, she has to take all her freiends with her
