And thank God it happened as an adult. But I figured out that if you don't do something back they will continue the same behavior.
One person was an in-law who didn't like me and would say nasty things about me in front of me and others. I finally got fed up and said something similar - that I knew she was very self conscious about right back, out loud and in front of others. And it ended. Right then and there; she never said another mean word to me.
I didn't feel right about what I said because that is not my nature but I was just trying to stop someone from hurting me and that is the only way I could figure out to do it
