Dear Sonia,
 I am having a party for my 13th birthday. Can you come to my birthday party? It will be a wonderful party. My parents will help me organize it. You can listen to some pop music and you can see a big birthday cake. I think it’s much bigger than my mum made for me before. It is as big as a desk. Did you see such a big cake? It will be a special party, too. It’s also a ball. You can dance to the nice music. But you have to take a partner(伙伴). The party begins at 7:00 pm this Friday. Welcome to my house. If you come to my party, you will have a great time! Don’t forget to take a partner!
 Lily
