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”
A pet peeve of mine is when a work of fiction either breaks its own rules or real physics in a way that isn’t justified.
I’ve had people go “what do you mean X is unrealistic? It has magic flying creatures of course it’s unrealistic!”
A fiction should still follow its own rules, and should follow real physics to the extent it borrows from it! Anything else is just lazy.
