Oh, how deeply I relate to this quote...
"Once in Vermont, Mr. Yuan worried when people smiled and asked “What’s up?” “It was really awkward,” he says, “because I wouldn’t know how to respond and while I was thinking of an answer they would just walk away.”
(From: "The China Education Boom on U.S. Campuses", The New York Times, November, 5, 2010).
A bit like the story of my life here.
