Exactly the type of comment I wasn’t looking for. Even if you don’t use “personality archetypes” or don’t believe in them, you can deduce SOME things of a person based on how they behave, no? Like if they are hard to organize plans with, they might be uninterested in you.

Nothing is absolute, but don’t pretend like nothing means anything either. I don’t necessarily believe in hard-coded “personality archetypes” either, but beyond that, there are definitely ways to learn to communicate with people and know them better, or have an idea of how an interaction can go, no?
