Well it goes hand in hand. Everybody talks to everyone on facebook. Nobody posts on my Wall I have to post on theirs and I most likely won't get a reply back. As my roommate says "If you have to call them in order to do something and they don't ever call you, then they're not your friends." If you go by the 'calling me, texting me, leaving something on facebook, msn etc' I've got 2 friends, both of whom were my roommates. *shrugs*
