I love how the argument 100% of the time goes:

Person 2: "What? You don't technically need them, why are you saying that? You're obviously an idiot!"

¯\_(ツ)_/¯

Like, I could totally eat dinner without using a chair. It's not necessary to the dinner eating experience. But I'd much rather eat while sitting.
