Dear James,
How have you been lately? Remember tommorrow we are going shopping together? I'm very excited about that. I have just surfed the Internet and looked for a good place to go. There's a place that I really want to go. It is called "The Secret". Have you ever heard about it? What do you think if we go there tomorrow? I can spend a total of about 500 Vietnamdong. I intend to buy my dress for the next party in my school, hope that I will choose a suitable one. 
Please tell me your opinion and write to me soon, I'm looking forward to your letter.
(Your name)
