They’re built differently depending on where you live in the states and your environment. I know y’all love staying ignorant to feel superior but this one is still pretty dumb. People in Japan practically have paper walls and I don’t see you guys all up your snobby butts about that. Xenophobic turds. It would take people 10 seconds to learn why some of our houses are built the way they are but they won’t bother if they haven’t by now because they prefer the ignorance.
