I am a combination of lazy/welcoming/aware that it works as promo, when it comes to Facebook. So I have quite a lot of 'friends' that I either met once or who know someone who I know. I' m generally not bothered (My FB page includes a bit of self-publicizing of my work).
But a while ago, I had a minor spat with someone in the category of 'not actually sure who you are but we have some mates in common'. This person threw a MEGA tantrum, allegedly deleted own FB account because I am such a horrible person (and several of the mutual acquaintances send e lots of 'You are a really bad person' messages).
Let's say I gave about five percent of a fuck anyway. But now, for some reason, posts from this person are showing up on my FB feed again. And apparently we are 'friends'.
Not entirely sure whether to ignore, unfriend, or send a passive aggressive message along the lines of 'Oh, have you decided I'm not a cunt after all, or something? Or are you just in need of something else to have a tantrum about?'
