kids learn that they fucked up by having adults tell them "you fucked up." part of growing up is learning to figure this out on your own; by the time you hit adulthood, you should be able to infer when you fucked up without help. adults show each other that we fucked up more subtly. our shoulders shrug, we sigh, our faces get sad. we usually don't say "you fucked up," because that's how you talk to children, not other adults.
fucking up at berkeley high often got you talked to like an adult, not a child.
