For me it’s time signatures in music. I grew up playing instruments, played in several orchestras, etc. But no matter how many times someone tries to explain time signatures to me, it makes no sense. I don’t understand why people place such importance on it. To me, notes have a pitch and a duration, maybe some dynamics. That’s it. I don’t understand why people try to needlessly complicate it. It doesn’t give you anything.
My wife will hear a song and go “Oh neat, it’s in 5/8.” And I’m like “How tf do you know that, and why does it matter?”


Possibly related question: Are you one of those folks without a mind’s eye? What’s the space catholic term for it? aphantasia?
No, I have a mind’s eye. If the recipe says “stir until the sauce reaches a creamy, glossy texture” I can picture it perfectly.
