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 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！
