I was friends with a group of 9 other women. We all met at a toddler group when our children were small, several years ago, and have had regular coffee mornings/nights out.
One member of the group is quite a gossip and likes to divide and conquer a bit. The problem is, she causes all kinds of problems and divisions but somehow always manages to talk her way out of things. If we meet up and several group members can't come, she will bitch about one of the members that isn't there, or just generally dissect their life/how they parents their children/their house.
She has caused no end of small arguments and fall outs with her shit stirring, so much so that we have now split up into three smaller groups that meet up. Yet despite being the root cause of it all and of all the problems, she has managed to stay friends with everyone and gets invited to everything. She'll do things and then make out that she is just clumsy or socially not great, and her behaviour seems to be overlooked.
I know it sounds very childish, but it really bugs me. I seem to be the only person that can see through her and see her true behaviour.
