I am one of the people that go and wade through my " Facebook friends" and promptly unfriend people . Why? Variety of reasons.. usually its a combo of my disinterest in there posting or they get pissed about what I post ( LOL My Facebook, I post what I want) or I just realize that somehow or another I wind up seeing a old classmate through a ole friend, we friend each otherr chit chat back and forth a couple times and like a few things and then it trails off.. It's the nature of the beast ( Facebook)
Maybe i'm a hardass... Life is short and I just really don't care if someone were to unfriend me or block etc ...
