It does happen with family, which is why I went no contact with a lot of them. I don't get out much, and things like this are part of the reason, but I used to go to day programs for people with mental health issues, and it would happen a lot there too. More often by staff than by other clients.

Common techniques are:

Countering every statement I make, no matter how innocuous. "Aw, what a cute dog."--"Puh. Nasty ankle biters." Then when called on it, "What's the matter? Aren't people ever allowed to disagree with you? Other people are entitled to opinions too." Which is pretty much what's going on with the Facebook conflict.

Pouncing when I use a word like "innocuous," as in the last paragraph. "Why do you have to show off how smart you think you are? Speak English, like the rest of us."

No-win situations, as in I follow their advice and avoid words like "innocuous," and then I get lectured because I come off as fake. "Stop putting on an act, and be yourself."

Heavily implying something, and then denying having said it. Example, "I don't believe it happened as you say. That's not the pattern. I suspect you're not being completely honest with us." Later, "No, I didn't call you a liar." It's true they didn't use the exact word, "liar," but they sure danced all the way around it, didn't they?
