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"
However annoyed you are when somebody corrects that, it's how annoyed they are when someone makes the mistake in the first place.
Not saying anyone is right, but I am saying the one making the mistake, the one correcting, and the one complaining that it's annoying to correct them, are all petty bitches.
