Last year I lived in Chile for half a year as an exchange student with the American Field Service. Compared to most visitors, I didn't travel much. I lived with a Chilean family and had the responsibilities of any Chilean teenager. I went to school every day, in uniform. I had good days and bad days and days that I didn't understand.

    Chuquicamata, my host community, is a mining camp in the Atacama Desert. There is no disco, no shopping center, no museum or beach. Driveways must be watered daily to keep the dust down.

    When I arrived here, I was scared. It was so different from the urban middle-class America I was accustomed to. There were lost dogs on the streets, and a constant cloud of brick-colored dust came from the mine. There was no downtown, few smoothly paved(用砖石铺的) streets, and little to do for amusement. The people worked extremely hard. Rain was a rare phenomenon; earthquakes and windstorms were frequent.

    I had studied Spanish for two and a half years and was always one of the best students in my class. But in my first week in Chile I was only able to communicate and needed one person to whom I could explain my shock. I couldn't speak the thoughts in my head—and there were so many.

    Most exchange students experience this like me. Culture shock presents itself in everything from increased aggression towards the people to lack of appetite. I was required to overcome all difficulties. Being an exchange student is not easy.

    As time passed, everything changed. I began to forget words in English and to dream in Spanish and love Chilean food. I got used to not depending on expensive things for fun. Fun in Chuquicamata was being with people. And I took math, physics, chemistry, biology, Spanish, art, and philosophy.

    But the sacrifices were nothing compared to the gain. I learned how to accept as well as to succeed in another culture. I now know the world is my community and have a much deeper understanding of both myself and others.
