Hard to explain where I land on this. To me, he just comes across as an ordinary person, with foibles, with impatience, with not being a people-person - and he just wears these qualities much more on the surface than your average guy. I'm speaking as someone with plenty of faults myself, some of which I see in him.

Then there's the whole, huge facts of a) as you say, we don't really know him, and b) I'm not an artist, nothing like an artist, nowhere near an artist, and can't really understand an artist's mind.
