I am NT, and it's just part of the way we talk to people, in the end its just a collection of all the things. To understand someone in the best possible way, of course it's easier to see the whole picture - body language, intonation, face grimaces, voice tone etc. But it doesn't mean that we can't or don't want to understand a person who doesn't do all that at once. At least I can say that foe myself. I'm an inquisitive person, and I will just ask questions if I don't understand something, that's what I kind of expect from others too - to just communicate however we can with one another without judgement.
