My Brother Birthday

Mark is my brother. He is 11 years old. His birthday is on Saturday. We have a birthday party in our house. My sister and I buy invitation cards because we want to invite his friends. My mum makes a birthday cake. My dad buys balloons. Mark likes balloons very much. We decorate the house. We also buy presents for him. We buy a new blue bike because his bike is old. He wants to have a new one. This birthday party is a big surprise for Mark. I hope Mark and his friends have some fun together.
