Remember five years ago when no one had Facebook and you didn't know what the guy you took high school biology with was having for lunch?. “Remember how that was fine? Let's go back to that.” His proposal: a new holiday on Nov. 17 called “National Unfriend Day” that will allow you “cut out some of the friend fat in your life.” Post a status update asking for help moving. "The people that respond? Those are your friends. Everyone else isn't." Source
