I came to study in the USA a year ago. Yet I did not know the real American society until I injured (伤害) in an accident, because after the accident I had to see a doctor — and to court (法院). After the accident, my roommate called a doctor for me. I was very grateful and decided to repay him one day. But the next day, he asked me to pay him $ 200 for what he had done. I was very surprised. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible (负责) for my injury. I’d have to have a good lawyer (律师).
