以what a fool l was为题写一篇英语作文50字

Last week I saw an old woman begging near a supermarket.She was old and lame with dirty clothes.She picked things from the rubbish-bin and looked tired.I felt so sorry for her so I took all the cash from my purse and game it to her .I told her to buy something to eat ,she thanked me with a smile and hurried away.I was very happy until the shopkeeper came out of the supermarket and told me that the old woman lived near by with her children.She came to the supermarket just to look for fools like me to offer her money .What a fool I was!
