in retrospect the funniest of the reasons I was misdiagnosed as allistic (as in a guy who claimed to be a doctor specifically told my parents I'm not autistic I'm just weird) as a kid was that one of the main diagnostic things they use is seeing if you misinterpret figures of speech, and apparently they weren't prepared for the possibility of a child with a linguistics special interest giving them an infodump on the history and nuance of the idioms they're asking about
