Carl，

　　I came to visit you this afternoon, but you were away. I want to invite you to my birthday party at my home. It'll start at 7 p．m. this Friday. I will ask my friends to pick you up, and they will give you a call in advance.

　　At the party, I will first make a short speech to express my appreciation for my family and friends. Then there will be a big cake and a big meal. Afterwards, we can sing songs, play games, and watch TV. If you have any amazing ideas for the party, please let me know.

　　Yours，

　　Li Hua
