I think she has oversimplified NPD somewhat.
I’m better than you. And thats more or less it!
If only it were that simple, and if only they were that easy to spot!
In my experience they dont get the admiration they need by putting everyone around them down. Charm featured pretty highly in the day to day goings on. My H is a highly likeable chap, hell yeah, but ask him what he thought of those he charmed?? Ask him to tell you their name or anything about the person he just spend 2 hours chatting to. He knew how to touch an arm or a shoulder to make someone feel special - knew the body language to engage, and he used those skills, but couldnt give a hoot about the person. The person rarely knew that.
it took me years to work out that he didnt care. That every time we sat and talked about “us” he could not actually recall anything that I had said. I never knew that nothing touched him.
He didnt annoy people. Why would he? Whats to gain in that? Only I learned over years of his inner arrogance and how little anyone meant to him. Charming everyone around him, making people laugh and engage with him and think him a great guy was his thing. Only I knew that his sense of humour was not real, that it is merely a tactic to gain admiration.
He would have been “floored” had it not worked, but fortunately for him, it did and does work. These are not completely stupid people going around demanding that you like them and being obviously pissed off when you dont.
People still say to me OMG he was SUCH A GREAT GUY! yea he was, on the face of things.
She has read a book or two and she identifies what she has read with a “type” of person that she feels is highly recognisable. Maybe it is that simple? Just not in my experience!
