That, and as soon as you try to make them face anything they've done wrong - with proof/facts - they'll escalate the situation and start discrediting, gaslighting, even threatening you while having the same conversation. Of course, later they'll deny they ever did such a thing - even though they would do it anytime a discussion arose about their behavior and their lack of taking responsibility.

I've tried having logical, sound, calm conversations with my narc mother or my narc ex and both of them would react the same. Though he would escalate to tossing furniture in his tantrum. He never physically harmed me, but throwing a chair into a window does shut down a conversation. And he knew it was an easy, unpleasant threatening way to end an conversation. With her, she'd just fake cry and get her golden child son involved. He'd storm into the room and intimidate and threaten, calling me a bully for daring to stand up for myself and shame on me for feeling I had the right to have a civil conversation about my issues in the first place. My GC brother ended up her most devout monkey and acted as her physical bouncer. They have a sick relationship.
