Yesterday afternoon, my aunt found an one-hundred-yuan bill in her purse gone. She didn't know what had been happened. In the evening, she received a phone call to her son's teacher, whom praised my little cousin on the phone. My aunt finally understood everything. A week before, my cousin found a fifty-yuan bill on the street. And then he gave them to his teacher. The teacher praises him in front of the whole class. My cousin was very happily. That was how he took the money from his mother's purse and gave it his teacher,telling his teacher he had found it on the street.
