Yeah, kinda curious, might also be one families customs vs the others, though. Might also be a family that became wealthy at the turn of the last century, and then got stuck in the way they thought they where expected to act, enforced via 'traditions' taught. Dunno, really.
The guessiest person I ever met was actually the mother of my last partner. She was, on the one hand, usually offended by direct requests, while also very much assuming and extrapolating things from anything indirect one said, to the point where she often became incredibly offended by things no one said, but that she heard. It was exhausting, to a degree, and my first instinct was that she was looking for things to be offended about, either consciously or subconsciously, but I also feel that I can't really judge someone for the way they perceive the world.
