I don't think I'm INFp but I do that too. I had a discussion with a friend about it, because this guy was saying that it's "bad" to "change" your behaviour for other people. The girl I was talking to about it tried to say it was really bad to "not change" when you're interacting with different people. And seemed to get kind of defensive. I myself, change, but I don't uhh.. feel the need to defend myself?

Anyway ,..I seem to remember her saying something about having different behaviour for different people.

I probably use "my" language more than other peoples language. I just have different sets of "my" language.
