I'm not sure, but I think he comes from a poor family and probably isn't very well educated--presumably mostly self taught. I assume he has "struggled" during most of his life (which likely hasn't been easy), so he ends up angry, temperamental, and generally difficult to deal with. Good luck! And,you're right... I don't think he can bear any criticism, nor can he easily deal with "no" as an answer. In that regard, as I said yesterday evening, he's a little like Donald Trump--and just says whatever comes to mind (without much control). The big difference is that one has money, the other doesn't... What a mess!
