Some people legitimately do just need that kick in the ass to discover they’re not doing something right. Maybe they didn’t have great parents (or they weren’t present at all) and never learned those habits. Then society is way too big on politeness and avoiding problems such that nobody ever takes them aside and tells them they need to be cleaning better.
This may legit be the first time he’s ever been told he smells bad and needs to clean up.
