Twenty years ago, my father, John, wanted to be a businessman(商人). He wanted to be rich. So he worked very hard and every day he went home very late. One night, when he came home after work, a robber, stopped him and wanted to take his money. My father was very afraid. He didn’t know what to do. Luckily a policeman came and caught the robber. My father thanked the policeman politely. Now my father is a policeman. He wants to help others.
