So how do you avoid....

people that you don't really want to have contact with when a mutual Friend keeps throwing them at you?i mean really, what the fuck! i have told them that i don't really want to know these people,that i don't have any thing in common with them,and if i wanted to know them i would find them my self.i know that I'm kind of a face book ass hole but I'm trying to improve,there are rules of engagement that nobody teaches you.fortunately there is no real consequences outside of irritation,at least so far.i suppose that it could go really wrong but if you behave you should see any shit coming. the virtual world can be such a pain in the ass.if it weren't so god damn interesting and useful i would give it up. but it is .
