Ever drove yourself crazy not being able to understand the motives of a man? Well, you're not alone. There has to be a reason behind how basically every time a girl is nice to a guy it's perceived as flirting. And if god forbid a girl refers to him as her friend, BOOM, he's 'friend-zoned.' But, why? Can girls and guys just not be friends? Is it not okay to be around a guy, and laugh at his jokes, but not want to sleep with him?
