The common refrains seem to be 1) easy tests 2) seems nice in class and 3) is mean one in one. I wonder if 2 & 3 have anything to do with his shyness (as mentioned in the article) and his lack thereof when he gets to talking about math? Maybe he gets on a roll as far as math goes, but one-on-one interactions are more difficult? Or maybe he was busy coming up with this bad-ass paper and didn't want to extend his office hours? Either/or.
