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?”
Still not 100% on sarcasm, as an autistic person. Sometimes slips through the cracks for me when others use it. That’s despite me being a somewhat sarcastic person.
Luckily I’m from the UK, where you can pretty much assume 100% of everything being said is sarcastic and get by just fine.
