I love, love, love my female friends (I'm not really a guy's girl anyway) and am involved in a few hobbies that are made of mostly women, as well as nursing school which equals MUCHO estrogen. I don't even know if it's girls or it's just groups of people who are "competing," but there's always one blowhole in every group that can't allow people to just have fun without taking a jab. My favorite way to cope is just to blow them off and remember that...well, they can suck it. Just remember that there are usually two reasons people do crap like that: they are either kind of bitter and can't resist a jab or they're completely clueless and think they're just making conversation. Either way, don't let some sucker rain on your parade!
