making friends with people IRL from different countries has seriously been one of the most fun parts of college, I love hearing about people's hometowns and values. people are SO COOL. like yeah there's plenty of variety in the United States, but it's awesome to meet people that grew up in entirely different places and learn from them. I had a lot of friends of different cultural backgrounds before college, but everyone was either born in America or grew up in America.
and then you get the internet as just, like, a passive and sometimes unknowing source of persistent interaction of people from all sortsa different cultures.
