Guys, I was watching a movie called "When Harry met Sally" this weekend and was kind of awestruck by the claim which Billy Crystal, the actor made that a man and a woman can never be just friends beacuse everytime a stupid thing called sex comes in between the relationship and it eventually turns out to be an affair of love or something. I have never thought of that with my friends who are girls but the movie made me think twice on that. What do you guys have to say about this? Can a man and a woman just be a friend or when they become friend something more is likely to happen than a mere friendship?
