I suppose it's possible TG is a sociopath, although I don't know anybody who deliberately trolls like that. I still think it's far more likely that both people are poor communicators in that TG wants to get a precise and accurate answer from somebody who doesn't think about language that way and that NG is oblivious of the fact that TG is looking for a precise answer and will get frustrated with replies that don't answer his questions.
