Dear Bruce,
This Sunday is my birthday ,I’m going to hold a party in my house. As my best friend, I hope you will come. I think you will be free on that day. There will be cake, cookies, candies, pie and so on in the party. Lily said she would dance for me at that night. It must be very interesting and exciting. By the way, the party begins at seven o’clock, but I hope you can come a litte earlier to help me to prepare something about the party. I am looking forward to your reply.
