He cares about a number of things.
Oh, yes! He cares about how much "money" he pretends to have.
He cares about how many follow him on twitter.
He cares about how his "speeches" are received-- and fully believes he's good at speech-making.
He cares about how his hair looks-- and is visibly upset if anyone is critical of it's appearance.
He cares about his golf score enough, that he regularly cheats. This from people who have played "golf" with him.
He cares about everyone's perception of his man-junk-- and believes it's "large" (when many women have reported it's not, and doesn't function very well)
He cares all right... so long as it involves HIM-- AND NOTHING ELSE MATTERS.
