What would you think if a native of a foreign country you are visiting said to you: "your English is really good, where did you learn it?"

People say this to native English speakers who speak a foreign language all the time. But in my experience, if a native English speaker is visiting a foreign country and a local said something like that to them, they would take it as offensive and sarcastic. So why do we say it to people when we visit their country and they talk to us in English?<br><br>Example, I'm from the US. If I went to France and a French person said to me in perfect English "your English is really good, where did you learn it?" I would be like "shut up, you know my country is predominantly English speaking. So obviously I learned English growing up there."<br><br>French, German, Spanish, Italian, Portuguese; these are all countries whose populations are overwhelmingly a single nationality and speak one primary language. So to say to someone from these countries that their English is good is asinine.<br><br>So why do we say it to them? I think a lot of people have lost sight of reality.
