Depending upon the day and my mood, I can have a very perverse sense of humor. Given that type of treatment, I'd show up the at the next meeting, walk in boldly right up to the offenders, with a big "How ya doing tonight, ladies? SO good to see you again! You know, I think I'll just sit right down here with you so we can catch up. What's new?"
They'd either have to get up and move OR talk to me, one way or the other. Power mongers and bullies are, at heart, cowards and don't like to have someone shine the light on their behavior. At least, that's my experience. My advice is to get right back in their face!
