There is one word that is on the lips of Americans , day and night -"Sorry."
Once as I was walling on the street, a young man ran by      ,brushing against my handbag. Even as he continued on his .way, he       back and said "sorry" to me. Even in a rush, he didn't forget to apologize.
One day, after I bought some apples, the salesman was giving me the change, but I wasn't ready for it And a        dropped on the ground. "I'm sorry," he said while bending down to pick it up. I was      -why would he apologize when it was my         .
Another time ,I stepped          a man's foot in a lift At the same time, we both said "sorry"．I thought it interesting at first - was it really        for him to apologize?
Later on, an American friend           o me that according to the American ideas, the lift is a           place everyone should be able to stand in. After someone occupies a position in the lift, making it          for someone else to find a place to stand in ,isn't it necessary to       an apologize?
During my stay in America ,I gradually        that when friction（摩擦）happen in daily life, Americans don't care much about who is responsible.         Someone is troubled, a "sorry" is always necessary. The "sorry” would cool tempers       the other person is hurt. Perhaps this is why I      saw anyone quarreling on the buses, subways or street in America.
