It was Sarah's twelfth birthday last Friday. There was a birthday party in the evening. Her mother cooked delicious food and made a big birthday cake. Her grandparents bought a new bike for her. Her father bought a computer for her. And her mother bought a new dress for her. It was beautiful. After school, her friends come to her house. They ate good food. They sang and danced. At 9:00, they cut the birthday cake. How happy they were!
