阅读下面的短文，然后按照要求写一篇150词左右的英语短文

　　I once met a middle-aged stranger who said his money had been stolen at the railway station，so he had no money to go home. He begged for help from passers-by，but they all pretended not to have heard what he was saying and went by quickly. Then he stopped me and wanted me to give him the help. At first I could not accept that because I didn't think he was telling the truth. But when I saw tears in his eyes，I began to believe that he might be in the real trouble，so，just immediately I gave him all the money I had. When he took the money， his face turned red. Before he left，he expressed his great thanks and also said he would give back my money when he reached home.

　　When I came back to school and told my classmates about my story，they held different opinions. Some of them thought that I did a good deed（做了一件好事） to have given a hand to the person in trouble，while others said that I was cheated. Some even laughed at me and called me a fool who could not judge things in the right way. Now，I am really confused（困惑的）！
