The comments don't have to be nasty or overly aggressive. Anyone that's known someone who's passive aggressive knows better.
Been there, done that too. Had someone I was friends with for years turn on me because I questioned how she was treating others.... then had that exact treatment turned on me. Our mutual friends didn't see what was going on or even understand it, and the person would try to do little things here and there to bother me for a few months. I laughed most of it off because it was childish.
|Also, as evidenced by a few posters in this thread, many outside people can get caught up in it and not even know exactly what they are doing until its too late, then when they try to distance themselves from the bully, they in turn become a target|
