Suddenly I see why Kamiyama was the errand boy at his last school!
Hirai the flunker was great. "No I'm not talking to you because I have no friends and am seen as a loser."
The way Tanaka described Kamiyama is a way I often see him too, he jumps from out outcome to another as if there's one path he can go. 'Well somebody needs to be the errand boy, so therefore I should be, and this takes too much time so therefore I should set up a food stand so that I can study! And.. I need to add the sales tax!' It's like the way his logic works, it's so wonderful. What a great boy.
