[there's another long, irritated groan from Zangetsu. He hates it when people have a point that he can't contest. Hates it. Childermass is absolutely right; if Zangetsu dies because of some stupid manners, he won't get his contract wish.

There's another grumble and a sort of "ssnsnnnnnrrrrffff" as Zangetsu drags his hands across his face and nose]

Fine. Fine. But there ain't no way I can learn sufficient manners in that short a time period! What should I do? Maybe I should just pretend to be mute.
