I suspect it helps if you're a massive introvert and rather socially oblivious like me. Other than one isolated incident, I haven't had anything like this happen to me.
The isolated incident was at work, when we managed to hire what I can only describe as a sociopath. Had I not been the woman's line manager, I probably wouldn't have noticed, either - just that she realised she was not pulling the wool over my eyes so then went over my head to try to get me in trouble, which clearly I had to deal with as it was work and a hierarchy.
I'm not even sure I understand what a 'friendship group' is as I don't really have any. I have a few good friends, most on other continents as I made them decades ago. Plus some acquaintances. I sometimes think I'd like more friends as I can be lonely, then I read stuff here and think maybe not...
I do have one friend who runs (to me) randomly hot and cold. She's also constantly apologising for things that didn't even hit my radar. It's entirely possible I'm offended her left, right, and centre, unawares, and that would explain the cold periods.
I also just don't notice slights and digs and such. It only occurred to me months after the woman finally left work that a very strange thing she kept going on about was meant to be insulting me. At the time, I was just mystified, as it really didn't make sense. So, who knows, there could be people out there activitly trying to antagonise me and I'm simply not picking up on it.
