I’m a U.S. citizen, and I live with Chinese, British, and Brazilian roommates in Beijing. In China, introductions tend to elicit specific responses from locals, and it’s always an interesting representation of a given country’s warped reputation. When the Brit introduces himself, he’s often labeled a gentleman. When the Brazilian shakes hands, Chinese compliment him on his country’s soccer prowess and inquire whether he can dance the Rumba.
When I introduce myself as American, I’m frequently asked whether I own a gun.
