On last Sunday, Cathy and her parents went to the airport to pick up her cousin, Yvonne and her family.  Cathy was very excited because it was her first time to go to the airport. They took the breakfast at a fast food shop in the airport. When they were looking for Yvonne’s family, they saw many tourists . The tourists came from different countries. Some tourists had back faces and some had white faces.

After one hour, they could not see them . They were very worried. Then , they phoned Yvonne. To their surprise, Yvonne said that she and her family will come to Hong Kong on Monday. Finally, Cathy and her parents knew that they made a mistake .
