I've name changed for this, and sorry if it gets long. So my sister has this friend, they're actually very alike. They're the kind of people who crave popularity and people thinking they're cool. I'm not really friends with this girl but she added me on fb after I joined the gym she works at. I don't use fb much, mainly for selling pages and seeing cute pics of my nephews and nieces. Anyway this girl posts a lot, usually about what a fab mum she is, how hard she works as a single mum and #making memories. It's all a bit vomit inducing for me so i try and scroll past. She also has form for bitching about her ex online, She did last night about how he hadn't bought her a birthday card from their kids and it irritated me and I unfriended her. I hate seeing people air their laundry in public and tbh I've heard others making fun of her the way she goes on to. I make the mistake of telling my sister I'd deleted her after she asked if I'd seen last night's post. She got all annoyed at me and said "if you don't want to see her posts why not just unfollow her?" My response was that if I'd done that maybe she'd think I enjoyed her posts and I couldn't be bothered with pretending (if I'm honest I don't think this girl will notice I've got rid, I don't think I'm important). My sister thinks I should be supporting her, shes not as happy as she makes out online and some people need security from people and friends posts online. She thinks all women need supporting and I should be liking the posts but I don't see why I should fake it and if I'm honest I don't think people should rely on online presence I don't think it's helpful. I've got family and proper friends to think about I can't be being "supportive" of everyone. Was I too harsh?
