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.
rateexportpilot@Alice lol. I drive my wife crazy with this too.
That and I call paper towels "Kitchen Roll".
