#Q You know the saying “throw ya hands in the air like ya don’t care”? why bother doing that if you don’t care?
I am an expert because I don't give a shit.
A: Contrary to the statement of the person who supposedly doesn't care, this gesture is all for people who quite clearly DO care what other people think. If they truly didn't care, then they wouldn't be bothered that other people would think everything's hunky dory with them if they don't make some meaningless gesture in response to the actions of others, meant to express their disapproval and/or frustration.
If they didn't care, they'd just turn the TV on, or roll over and go back to sleep, or walk off, or take another bite of their pie.
