     I came to study in the United States a year ago. Yet I did not know the American society until I was

injured in a car accident because after the accident I had to see a doctor and go to court. 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 astonished. He had good

reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I’d have to have a good lawyer. Now that he had helped me to find a good doctor, it was only

fair that I should pay him.

      But every time I went to see the doctor, I had to wait about 50 minutes. He would see two or three

patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each

time. The final examination report only contained ten lines, and it cost me $215.

     My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew

very well the other party was responsible for the accident, yet he hardly did anything. He simply waited

to collect his money. He was so irresponsible that I decided to fire him. And he made me pay him $770.

     Now I had to act as my own lawyer. Because of my inexperience, I told the insurance the date I was

leaving America. Knowing that, they played for, time …and I left without getting a cent.

     My experiences taught me two things about America: firstly, in a country like America money is

everything. It is more important than friendship, honor or professional morality; secondly, foreigners are

still being unfairly treated. So when we talk about America, we should see both its advantages and

disadvantages.
