"Troublemaker" was what was given to my friend Peter by his teachers. They also said that he had no future and no hope! But now I suggest that anyone who said that should say "sorry" to him.Peter finished Grade Nine, and then he went to study at a technical college. He became a leader of a group of bad boys. After graduation he had nothing to do, so he just hung around by the market with his friends.It looked like nothing could change his life. It was not until the day that his father died. He left the boys and went to help his mother who sold food by the roadside.He really pitied his mum and wanted to do something to support her. He loved reading cartoon（漫画）books and had been collecting them for years, so he decided that he should sell them. Soon he realized that his books were very popular. So he made up his mind to set up his own business. He went around buying cartoon books from other people. He bought them for 25% and then sold them for half price.These days, he doesn't have to go around looking for cartoon books because there are always people coming to his shop to sell their old ones. He now has a monthly income of about 55 000 baht（泰铢）.He was a "troublemaker" to his teachers but he is a hero to me. If you are judged by your teachers as a "bad student", I suggest you ignore what they say. Just do your best in everything. Don't give up so easily. Believe me, one day you could be successful, too.What did Peter do after his father died?
A、He worked at a market.
B、He learnt to draw pictures.
C、He started his own business.
D、He continued his college studies.
