The worst person who had the worst problem with gossiping was the pioneer wife of an elder! And nobody would do anything about it. I remember being confronted by an elder for starting a rumor that I didn't even start...when here she was being a complete b;tch talking crap about everyone during service.
She would criticize me for everything from my clothes to my car...but never to my face! Always waited til I was out of the car at a door and then would hear about it later.
