I was just wondering to myself about how people use language at the borders of countries in Europe. Here in U.S. we have Canada on one side, which pretty much speaks the same language except for French Canada. And then we have Mexico on the other side, which I gather most of the people on the border towns end up at least learning basic English. I also note that this is not reciprocal.
So I was wondering, at least in Europe, there are many different countries speaking different languages very close to each other. I could see people in the middle, isolated part of the country speaking one language, but it would seem that being on the border it would be an obstacle.
How do the language borders fare in Europe?
