"SCHOOL IN AMERICA was easy, assignments sent in by e-mail, classrooms air-conditioned, professors willing to give makeup tests. But she was uncomfortable with what the professors called "participation," and did not see why it should be part of the final grade; it merely made students talk and talk, class time wasted on obvious words, hollow words, sometimes meaningless words. It had to be that Americans were taught, from elementary school, to always say something in class, no matter what. And so she sat stiff-tongued, surrounded by students who were all folded easily on their seats, all flush with knowledge, not of the subject of the classes, but of how to be in the classes. They never said "I don't know." They said, instead, "I'm not sure," which did not give any information but still suggested the possibility of knowledge."
