(Taking light-hearted commentary too seriously)

Something that young children have to grow out of is assuming that "if they know it, their parents must know it too", such as where they put (not hid, because "the parents know") the phone or the keys. As a child they haven't yet developed the, obvious once developed, concept of the individuality of knowledge and experience.

It does feel as if this regresses for long-term partners. The volume of shared experience must blur the boundaries of individual experience, or something.

My wife will often blurt out something totally incomprehensible to anyone but her, but since she's spent the previous 5-10 minutes reading / watching all the context leading up to it, she expects the rest of us (who may have only just strolled into the room) to know it to its core.

A punchline without context is nothing!

I do like the sideways glances my kids give me when it happens though. That's a shared understanding :)

This is so true, and painfully so. I was fortunate to have an epiphany a few years ago when I realized I was failing regularly to see my wife as a separate individual and part of the whole of "us."

More accurately, there were times when I probably viewed her merely and extension of myself. It honestly changed the way I view the world, and I somehow managed to extrapolate that understanding to life itself. It was a glorious dose of ego death, and one I sorely needed.

I've known lots of intelligent adults who assumed their particular knowledge was common knowledge. Most were polite about it and realized their mistake; a few were quite obnoxious and learned nothing.

Anecdotally, I wonder if/ to what degree this has been affected by increased job specialization, where a person who spends all day working (and perhaps socializing after) with folks who share their particular knowledge and jargon will then err when interacting with folks outside of that bubble.
