I agree - it's NOT a compliment, wherever it comes from. I'm an American who lives in France, and I get constant, constant feedback on my accent and have been told repeatedly that I speak "surprisingly good French" for an American. I understand where they're coming from, but it's really tedious.

I also get asked dumb questions about life in America. A lot of people ask if it's scary to live in America, their reason is: because everyone is a gangster and owns a gun! ;) LOL.
