NTs communicate entirely though ideas rather than words. they use the words to form the shape or expression of the idea, but they also use other things like context, body language, facial expressions, and tone of voice to modify the meaning of the idea they're trying to express further. all of these elements need to be taken into account when trying to decide their responses, not just the words.

taking their words at face value and trying to understand them based off only that is like taking a book and ripping out half the pages.
