How do you deal with rude people?
I work with someone who will act nice and if I respond nicely she will belittle me or say something rude. She a very controlling person and I’ve recently learned that control can also be tied to narcissistic behavior. I try to avoid these people but I can’t avoid everybody.

I don’t want to change who I am based on other people’s behavior. I want to be a nice person. I forget and let my guard down a bit sometimes. Today I tried to be reasonably polite and once again she made a rude comment and laughed at me. I said nothing in response because I don’t see the point in engaging with her. I immediately regretted that I had bothered to even be polite to her.

What are some things you do to deal with people like this?
