We've all removed somebody as a friend from Facebook at some point, be it due to ending a relationship on combustible terms, having an epic falling out with a pal or simply drifting apart from a former colleague. The sneaky bit comes in when you receive a friend request from somebody that was still your friend only a week or so ago and are a tad bewildered about the whole thing. One private message later and the response is usually, "sorry, my account got hacked so I had to create a new one and re-add everyone." In reality, you probably wrote a status or uploaded a couple selfie that bored/pissed off this individual enough to prompt them to delete you on a whim, and now they've got a bad case of the guilts and have come crawling back.
