The United States is a country that has to do things its own way. I remember in elementary school we had a unit on measuring temperature, and my teacher showed us a map of countries that use Celsius compared with the countries that use Fahrenheit. The only countries that used Fahrenheit at the time were the USA and Liberia. The US was really like, «I’m going to commit to this measurement, even if my sole ally is a country with a population less than half the size of Ohio.» That’s what I call standing your ground and being your own person. 

It’s not a complete fabrication to say that Americans can be a bit clueless about the customs of other cultures. Luckily, we have the people of Reddit to educate the American public on cultural norms outside of their immediate purview. u/RingoBingo14 asked Reddit, «What is something considered «weird» in the USA but is normal to the rest of the world?» and Reddit delivered answers that range from expected to mind-boggling.
