Dear Hoang
Hello Hoang, how are you? A few weeks ago, you transferred school but I did not have the opportunity to see you off, now you invite me to your 10th birthday, but tomorrow the time of your birth makes me wonder. for a long time. But then I decided: I'm going to go for your birthday, I'll give you a surprise! Please wait! You must be happy with this letter in your hand, right? Already a friend, you can do anything! I agree to attend your birthday party.
