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”
Canon is important to science fiction and comic book adaptations because the rules of those universes operate so wildly different from our own that it is important to put more work in keeping things consistent.
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.
I mean to paraphrase Brenan Lee Mulligan: “if you have magic that can teleport things instantly, giving the task of delivering letters to Earth’s slowest bird is animal cruelty.”
