One day Mabel was working at the shop. She sold three lottery tickets to a woman. The woman looked at the pictures on th e tickets. Then she threw the tickets on the counter (柜台) and walked away. “These are losing tickets,” she thought. Mabel picked up the tickets and looked at them. She was surprised. Then she was excited (兴奋的). One ticket was a winning ticket! “Excuse me!” Mabel called to the woman. “You won $ 50,000!” The woman came back to the counter. She took the winning ticket and looked at it “You're right,” she said. “I won $50,000.” The woman walked away slowly, looking at the ticket again and again. Then she turned around. “Thank you! Thank you very much!” she said to Mabel. Why did Mabel give the woman the ticket? Why didn't she keep the ticket? Didn't she want the $50,000? “Of course I wanted the money,” Mabel said. “But it was her ticket.
