The Politics of Friendship on Facebook

Maybe I'm old school, or maybe (though highly unlikely) I'm future-proof, but I honestly don't get the whole "Politics of Friendship" that often goes on, on Facebook. It just confuses me how people can easily add random people to their lists, not knowing a sausage about them, and as of such baring all of their life to the world. Don't they realise the danger in adding people that they don't know? Actually scrap that, cause I'm pretty sure I know the answer, and that answer is simply they don't think. After all these are the very same people who regularly enjoy 'deleting' those they do know and then six whole months later re-adding the same person with an excuse of "oh I accidentally...", yeah right, like deleting someone could be an accident in this day in age- you actually have to click around 3 times to delete a person and around 4 times or so to block a person, basically these people are an absolutely wonderful example of ass-talkers, that's right they talk out of their backside...Ironically you'd be surprised by the amount of times people believe that bull-poop. Usually it's people like me who don't usually delete anybody- because it's pointless (if I don't want you on my friend's list I'm not going to accept you and if I don't want you to see my posts no more ta-ta and welcome to acquaintances option). If you wondering how I even learnt how much effort goes into deleting someone- let's just say I used a willing test subject to see how "easy" it was to remove someone and let me say, too much effort!!!

Why do people even do it? I personally have no 100% clue but I can safely assume it is probably a combination of the thrill of control- the acting of god whom has control over all, jealousy, immaturity or lastly disagreement, which in itself is I guess an act caused by immaturity and loss of control.
