I came up with one...
I joined a very nice community choir a few years ago. People are so friendly to each other. As it is a community choir, there were no divas. I felt at home instantly, loved the songs and the way "the choir master" treated the members, even though I am not the best at catching all the harmonies, there were lots of people like me, and that was reassuring. No matter.
But along came a "know it all" woman, let us call her Jane, who clearly had had training, could read music, etc. So, sometimes people would ask the choir master questions to clarify things. I did twice in one session, and each time Jane, standing in the front row, would proceed to answer the question clearly posed to him, not her. After the session I told her how annoying, intimidating, and simply rude that was. I did not think she quite understood how important it was to maintain a friendly, non-judgemental atmosphere, but in the end she told me that she would not do it again.
But of course, she did it again a few months later. Then I just spoke to the Chair Lady of the choir Committee and she promised to talk to her, though reluctantly. She said she did, but I am not sure if she really did.
This was ruining my really enjoying the choir sessions, though I knew that I was not going to quit because of that silly woman. So finally, I came up with the solution, which I have not tried yet, but am going to definitely use: Next time she does anything patronizing like that, I would just say:
YES, MOTHER SUPERIOR! YES, MATRON!
I am very curious of her (and other members) reaction, but I think it should work, as nobody likes to be mocked and laughed at.
Please give us examples how you have dealt with adult bullies or in any conflict situations, creatively.
