My husband and I don’t fight very often, but one thing we do fight about is how he calls aluminum foil "tin foil" and he's like "IT'S THE SAME THING!" and I’m like "bruh, they are completely different metals, so please go consult the periodic table I've hung above our bed."
The periodic table above our bed is the other thing we fight about.
In defense of @KevBot, the periodic table used to be over our desk, but I randomly decided to move our bed to that wall so now we have a really romantic periodic table over our bed rather than the previous and almost-as-romantic Helsinki transit map over our bed.
