Steve and Yaser first met in their chemistry class at an American university. Yaser was an international student from Jordan. He was excited to get to know an American. He wanted to learn more about American culture. Yaser hoped that he and Steve would become good friends. At first, Steve seemed very friendly. He always greeted Yaser warmly before class. Sometimes he offered to study with Yaser. He even invited Yaser to have lunch with him.

But after the term was over, Steve seemed more distant(疏远的). The two former classmates didn’t see each other very much at school. One day Yaser decided to call Steve. Steve didn’t seem very interested in talking to him. Yaser was hurt by Steve’s change of attitude. “Steve said we were friends,” Yaser complained. “And I thought friends were friends forever.” Yaser is a little confused.

He is an outsider(局外人) to American culture. He doesn’t understand the way Americans view friendship. Americans use the word “friend” in a very general way. They may call both casual acquaintances(熟人) and close companions(伙伴) “friends”. Americans have school friends, work friends, sports friends and neighborhood friends. These friendships are based on common interests.

American society changes rapidly. Studies show that one out of five American families moves every year. American friendships develop quickly, and they may change just as quickly. People from the United States may at first seem friendly. Americans often chat easily with strangers. They exchange information about their families, hobbies and work. They may smile warmly and say, “Have a nice day.” or “see you later.” schoolmates may say, “Let’s get together sometime.” But American friendliness is not always an offer of true friendship.
