NF's in my experience are the kings and queens of the following back-handed apologies:
- I'm sorry you feel that way
- I didn't mean to bring it up
- I'm sorry it upset you
- I don't know how I could've acted otherwise
etc... none of which actually acknowledges any fault on their own part except for unintentionally causing your negative emotions, but never, never for your emotion being VALID because what they did was WRONG.
Naturally, I'm talking about when they're behaving badly... which all of us do sometimes. This is what I've come to recognize though as a particular type of behaving badly that's very NF... most of 'em are groovy and cool though, mosta the time.
