> casually agreed upon "I do task X and you do task Y"

Tangentially, I hate that people express hollow intentions, like “We should definitely hang out some time.” Why would you say that, when it's not your intention? Of course, I understand that people say such things because of social conditioning. But, such language tends to upset people regardless of neurotype. One could simply say “It was nice to see you. Goodbye.” It would be all right.
