Last Saturday was Linda's birthday. Betty, Li Ping and I went to her home to have lunch. We bought some gifts for her. I bought a new doll for her. Betty bought a birthday cake for her. Li Ping bought a box of crayons for her. We ate some delicious food in her home. Then we watched TV at 2:00 in the afternoon. At 4 o'clock we went to the park to fly a kite. We had fun that day. We all said "Happy birthday." to Linda. Linda was so happy.
