I mean the other 2 countries, Canada and Mexico, how similar are both of them to United States?? Both countries have a similar economy and democracy etc, and I think those two countries share things like supermarkets, stores, etc. I suppose the cultural differences are not a lot, that is very nice.
It’s funny that person assumed I’m American, as well. Born and raised in London, UK, yet lived in America for a number of years.
My outlook is entirely from an outsider perspective, and the differences in culture is very, very evident like the examples you mentioned.
