A pet peeve of mine is when someone says "be careful" after something happened. It is extremely common in Hong Kong culture, it is basically the rule that someone will say this if someone else has some minor misfortune like stumbling, dropping something etc.
People say this out of the goodness of their hearts and as a form of comforting word, and I should get over it, but no matter how long I've lived here, it really gets on my nerves.
To me, it hits as arrogance, nosiness, fake concern and a waste of breath. People don't mean it as any of those things, but I cannot make myself appreciate it, I can only bite my tongue.
1. You don't know if the receiver took insufficent care according to their view. Maybe they consciously accepted a tradeoff because they directed their attention on something else.
2. Maybe a reasonable observer before the fact would have said they were taking the appropriate level of care, but shit just happened.
3. Maybe they don't consider whatever happened a problem. Maybe they don't want to draw attention to it and just want to move on.
4. As advice, it's 100% based on hindsight. Where were you when the person made the decision to take whatever level of care they took? Where was your advice as they were taking whatever action they took?
5. It's unsolicited, extremely unspecific advice and offers zero insight. What other thing should they have taken less care with?
@clacke I agree, it's social filler, much as "Bless you" when someone sneezes. I guess it's recognition that a mistake or (loud noise) has been made in a public space, and it acknowledges that awkwardness and allows it to defuse. Same as loud yawns or burps (from either end).
