Today is my thirteenth birthday. I got up early in the morning. Mom was cooking, and Dad was out. When Dad
came back, he brought a new blue bike. " This is your birthday present. Happy birthday!" Dad said. At the same time,
Mom came out of the kitchen with a big smile. She held a birthday cake and said, "I bake it for you." I felt very happy
and kissed them. I will never forget the day.
