People with personality disorders lack something called "object permanence" - i.e, the concept that things exist independently of your experience of them. For instance, most people aren't impressed by "Peek-a-boo" past a certain age, because they eventually learn that

• When Trump says "you" or "they", he is probably actually referring to himself. (When he actually refers to another person, he will do so by name).

• When Trump says "everyone", "people", etc., he probably actually means "someone, at some point".

• When he says "nobody", he is also referring to himself, but specifically referring to something that he is deeply, deeply ashamed of. Pay attention to these. This is when you know that you really have him in a corner on something. "Nobody cares" = "I care." "Nobody knows" = "I know". "Nobody is calling Sean Hannitty" = I have been calling Sean Hannity daily, begging him to back me up".
