this saturday is my birthday and 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 at that day. there will be cake, cookies, candies, pie and so on in the party. lily said she will 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 litter earlier to help me prepare something about the party. i am looking forward to your reply.
