If there's anything I absolutely can't stand, it's this: some acquaintance of yours (not a best friend or anything) posts a status update on Facebook. It's witty, it made you laugh, and what's more, you have the perfect comment for it. So instead of simply 'liking' the status, you comment on it, certain that they'll get a laugh out of it, if nothing else.
Five minutes later, you happen to glance at your home page again and find that your carefully crafted comment was deleted.
It wasn't offensive, it wasn't inappropriate, it wasn't insulting to anyone in any fathomable way.
So why did it get deleted? Is it merely this friend's 'polite' way of dismissing you without actually removing you from their friend list? Are they trying to eradicate you from their life without having to tell you to your face that they hate you? Is this bloke such a control freak that if your comment isn't exactly the one that he was expecting when he posted that status, he deletes it so as not to 'muss up' his page?
Perhaps I appear to be overreacting too soon and I suppose you, dear reader, are perfectly justified in thinking that. To that I say this: one incident, even two or three, is forgivable; even more so if an explanation for it is provided.
Having every. Single. Comment that you ever post on anything of this friend's deleted, however, is not. Especially if you only comment on something he posts once every three months or so. (Deleting obvious stalker comments is a completely different discussion.)
If they didn't want to be your friend, why did they accept the stupid friend request? Obviously they have some kind of major problem with you, why didn't they just click 'Ignore' and spare you (not to mention themselves) this kind of aggravation?
And if you happen to be one of these selective-reality-obsessed chronic comment deleters, this is all I have to say to you:
If you don't want people to comment on it, don't even post it on Facebook in the first place.
