~*~friend Or Foe?~*~

Friend Or Foe? this question is on my brain. A lot of people say there a friend but they cause you pain. What is really a friend? What is really a foe? I think friend are something you should keep even while you grow A foe is someone who might not be your enemy but isn't your friend either. Would a friend talk about you behind you back? Would a friend act like one person around you and Totally different when there not? Would a friend act like a bytch? well, sometime. I do with My best friends but they understand where I'm coming from. Can anyone answer me? What is a Friend? What is a Foe?
