He does this on purpose, to get under people's skin.  It works, but it doesn't work well for him.  He comes off as a crotchety, angry, spoiled, old man.

Yeah, this is the guy the USA should send to China and elsewhere to "represent us"?????  OMG.  I can tell you right now that damned old geezer doesn't represent a THING  I stand for, not one single thing.  He lives in lala land almost constantly.  Reality isn't the major space he occupies.

IOW, he's a DIMWIT.
