He was a single father, raising a 5-year-old boy alone. He worried about his son growing up without a mother to care for him.
One day he went away on business, leaving the child alone. He was worried about the child all the way, not knowing if he had eaten. But his child always told him not to worry. He went home quickly after finishing his work.
When he got home, the child was deep asleep. He was tired out. When he was about to sleep himself, he was surprised to find an overturned bowl of noodles under the quilt. He spanked his sleeping son angrily:"Why are you so naughty, making the quilt dirty? Who will wash it?" It was the first time that he had hit his boy after his wife's death.
"I haven't," the boy explained with tears in his eyes. "This is your supper, Daddy." In order to let his father eat dinner as soon as he got home, the boy cooked two bowls of noodles: one for himself, the other one for his father. He was afraid his father's noodles would get cold, so he placed them under the quilt to keep them hot.
Hearing this, the father hugged his boy tightly without saying a word.

　 I came to study in the United States a year ago .Yet I did not know the real 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 wanted 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(尽责的，负责任的) for my injury, I’d have to have a good lawyer. And only a good doctor could help me get a good lawyer .Now that he had helped me find a good doctor, it was only fair that I should pay him.

　 But every day 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 consisted of ten lines, and it cost me $215.

　 My lawyer was all smiles the first time we met. But after that he avoided(避免) 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 dismissed(解雇) him. And he made me pay him $770.

　 Now I had to act as my own lawyer. Due to my inexperience, I told the insurance(保险) company the date I was leaving America. Knowing that, they played for time…and I left without getting a cent.
