Dear Tamara,
Thanks for the birthday card! I'm really looking forward to the weekend. I'm going to have a party on Saturday night.
Mum and I are going to go shopping on Saturday morning. We want to buy some food and decorations for the party. Mum's going to make her special pizza and a birthday cake. I am going to make sandwiches. In afternoon, my brother is going to help me decorate the house with streamers. Then, I'm going to plan the music for the party. On Sunday morning, I'm going to help my Mum clean-up.
Well, I think it's going to be a great party. How are you going to spend your weekend? Write soon.
Love,
Sharon.
