For years now, all guys can talk about is the "bro code". They're given guidelines for wingman-ship, man-on-man competition over women, rebound hookups, even what to get their buddies for Christmas—every facet of their friendships with other men is totally covered. They never have to ask themselves, "is it OK to hook up with this girl if my friend has already hooked up with her?" or "what should I do to help my friend going through a breakup?" They already know the answers—the bro code dictates their friendships for them. Us girls, however, have a slightly shakier foundation when it comes to friends and guys. Pretty much all we have to go on are the wise, wise words of Gretchen Wieners in Mean Girls: "Ex-boyfriends are just off-limits to friends. That's just, like, the rules of feminism!" But are they? What exactly are the rules when it comes to exes? Are ex-hookups off limits? What about ex-things? And what's a friend's responsibility when it comes to breakups, make-ups, and shakeups in her BFF's love life? Basically, what's the girl code…and how does it compare to the ubiquitous guy code? I asked girls and guys what they thought the rules were when it came to friends and the opposite sex, and the results may convince you that men and women really are from different planets!
