Last Saturday l went to a bookstore to choose some books but found my wallet going when checking out. I panicked immediate as the wallet was a birthday gift from my best friend. Besides, they contained about 500 dollars, which I had earned by working hard as waiter in a fast food restaurant. However, I quickly left the queue and began to search the area in that I had been reading.  Then a girl in her twenty came up to me. It was turned out that she had been waiting for the owner of the wallet. In my delight, I not only get my wallet back but also made a new friend.
