Yesterday was a lucky day for my cousin. In his way to the office, he leaves a bag with 3000 dollars in it on a bus. A day late the money was returned to him. He didn’t find he has lost the money until he returned to his hotel. He at once rang the bus station to ask that if anyone had found the money. People there said that no money had found. That evening, He received the call at his hotel from a bus driver. She said that she found the bag on the floor of the bus. Inside the bag, she found her phone numbers on his name card. My cousin felt very happily and he offered to give her 30 dollars, but she didn’t take it.
