All friendships require a certain amount of chemistry, but when two people of the opposite sex become friends, sometimes those friendly feelings can start to resemble something more like sexual tension.Male-female friendships can be an emotional minefield of hidden desires.Does this mean you secretly want to jump into bed with all of your friends? Of course not.But do you ever wonder how many of them might be interested if the opportunity presented itself? Maybe you and your platonic(柏拉图式的) friendship are just a bad breakup and a bottle of wine away from crossing that boundary and hooking up(结合).So can two people of the opposite sex ever really be “just friends?” The Hollywood answer to this age-old question is a decisive HELL NO.On screen, male-female friendships always turn into something more.Harry and Sally, Chandler and Monica, Jim and Pam...do reed to go on? Even the characters in Just Friends wind up becoming much more than the film’s definitive title suggests.Cinematic stories dictate that when reasonably attractive men and women befriend one another, they are always on the road to romance, whether they realize it or not.But how much truth is there to this friendship as foreplay (性爱前奏）theory? Not a whole lot.Real life isn’t a romantic comedy.Men and women go to school together, work together and hang out in plenty of platonic settings without falling hopelessly in love with one another.Last year, a close female friend of mine moved in with a new male roommate.My immediate reaction was, “You two are definitely going to sleep together.” It seemed to me that a single man and woman living under the same roof would inevitably end up doing it.Much to my surprise, the roommate romance never happened.Almost one year later, the two of them have never even come close to seeing each other naked.Instead, their way of life has come to resemble a sexless marriage.They cook for each other, argue over domestic chores and insist that they never, ever think about each other “that way.”
