Most truly American culture celebrates conservative values like family, freedom, and rugged individualism. There are groups in Eastern Europe that do cowboy/western re-enactments and I hear it’s wildly popular. I think a 4th of July parade with hokey floats and high school marching bands where people line the sides of a small town Main Street is an example of uniquely American culture. As is a backyard cookout.

When my son was in 7th grade (c. 2008) at a private Christian school, they hired a Ukrainian guy (who had married an American and recently moved here from Ukraine) to teach 7th grade. The dude chastised my son and other kids for their exuberantly friendly behavior - such as high-fiving each other. He told me, when I asked why this was a problem, that in his country this would be considered improper behavior in school. He wanted the kids to be somber little scholars…. I told him that as long as they were not overly disruptive in class, I thought the kids were being normal happy 12 year olds and high-fiving was part of their culture, which ought to be respected.
