My name is Grace. Today is Sunday. It is a nice day. It is also my grandfather's birthday. He is 80 years old. My parents and I go to his home. We don't get up early because the alarm clock (闹钟) doesn't work. We don't have much time for breakfast. We go to a supermarket to buy some fruit and a birthday cake at eight thirty. Then we go to my grandparents' home quickly. We get there at 11:15. My grandparents are very happy to see us. We have lunch at 12 o'clock. After lunch, we play chess with my grandfather. It is interesting. We go home at about four o'clock in the afternoon. It is a happy day.
