What's the most petty/pointless/pedantic hill you're willing to die on?
For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don't want to reach under the roll to take a piece! That's ludicrous!
That or my recent addiction to correcting people when they use "less" when they should use "fewer"
As I've said before, the distinction between countable and uncountable quantities is lost on most people nowadays. In my opinion, the rampant overuse of the word "amount" (instead of "number") is the clearest indicator of this problem.
