I use Instagram. Not much and I post sparsely. I unfollowed 3 people last night. They're not really friends, just people I've met a couple of times through other people and have been in the same circle for a few years. I see them once in a blue moon and I don't have their numbers etc.
I unfollowed three people, and 2 of them had messaged me within a couple of hours to ask why and one told kid I was rude. I don't really know what to say 
WIBU? Am I obliged to follow them? I doesn't mean I don't like them I just barely know them and they don't interest me. I hardly use social media and didn't realise some people are so hurt by this kind of thing. I don't know how they even realised that I had unfollowed to be honest!
