I dunno. I’ve always been an avid reader and good with words on occasion but on most occasions when debating or trying to get a point accross I stumble and can’t think of the right word or lose my train of thought or whatever. He’s not a good speaker. But it might have nothing to do with his “book smarts” or lack thereof. There might be some kind of learning disability.
I was told very EARLY in my education:
“NEVER use a word you can’t pronounce or that you can’t define.”
Keeps you out of a lot of trouble.
