On Saturday, we found an entertaining way of ridding ourselves of this unwanted attention (we just wanted to go out and have a good time, not babysit beginners English speakers). Whenever we were accosted (at least 5 or 6 times in the space of a few short hours), we would answer, "China", "Burkina Faso", "India" or another country we were clearly not from. When they didn't believe us (god knows why), we'd say that not every person from a country looks the same and it's very racist to think so. We were left alone pretty quickly. Try it sometime. It's fun.
