this! >>> scarcely acknowledges there is a factual world out there, inhabited by other persons

I suspect this even applies down to the personal relationships.  I am reminded of watching parts of the inaugural ball on teevee, I saw him dance with Melania, and this is before I had learned much about his narcissism. I reacted like this: what kind of man dances with his wife that way on such an occasion? It 's very clear he gives a shit about her, she is like a prop, he's not even looking at her face. For most anything like this would be a highlight of their marriage, celebrating a great victory in their lives, you see joy in their faces, not here. It was just very strange until I knew more about his psychopathy.

Now the few times I have seen him praise Melania for some deed or say something nice about her, it sounds very much like someone who had be trained to do that because they have a handicap in relating to people. Someone sometime in the past, like an image advisor or something, yelled at him and said you're supposed to say nice things about your wife, ya know. And not talk about her in the third person all the time either, like she's an object that you own. And he goes oh I see, I never thought of that! I will try! That's the way I see him when he compliments most people now, it's a bit different than being insincere, it's more like I'm trying but I don't know how to do this. Because the only being he truly thinks about is himself, that is his only frame of reference.

Not even pets. No history of that either, of loving pets. I used to think animal lovers who can't show any feelings for humans were creepy, but this Trump syndrome is worse!

I think Ivanka is perhaps the only human that he's close with, that he relates on a feelings level, as alien as it might be. But that's because to him she's a mini-me, but in an idealized perfect female form that he helped shape both nature and nurture.
