    "Sorry" is a word that people in Britain often say in their daily life.
    One day, while I was (walk) on the street, a young man ran by hurriedly, brushing (轻擦) against my handbag. He continued （继续） his way, but turned and said "Sorry" to me. Even in a rush, he didn't forget (say) "Sorry". A few days later, after I (buy) some bananas, the shop-keeper was passing me the change, but I wasn't ready it and a coin dropped onto the ground. "Sorry, madam." he said while bending（弯腰） to pick up. I was (surprise) why he said "Sorry" to me. Another time, I stepped（踩了） on a man's foot at the entrance（门口） to a cinema. At the same time, we both said "Sorry".
    (slow), I got to know that when something unpleasant happens in daily life, the Britain   don't care much about who is wrong. If someone is in trouble, a "Sorry" is always necessary. Perhaps that is I seldom see people quarrel on the buses or (street) in Britain.
