The day before yesterday, I went to the bookstore where is near our school to buy a dictionary. It was Saturday, so there was many people. Under the help of the shop assistant, I quickly got the book I needed. I was about to leave when I found someone trying to steal the man's money. Although nervous, but I tried to think a way to help him. Suddenly a good idea came to me. I stepped on the man's foot on purpose. As I expected, the man's scream gives the thief a fright, who quick walked out of the shop. After hear my explanation, the man smiled and showed many thank to me.
