Dear Lan,
It has been a long time since we last seen each other. How are you and your family doing? Please send them my best regards and wishes.
There is one good new that I really want to share with you. Next week is my birthday and it would be great if you could come and join us. It will be a lot of fun, for I have invited a lot of our classmates, and also I will prepare delicious food. The most interesting part is that we are planning to have a dance competition along with some games (of course, nice rewards for the winners).
I'm looking forward to seeing you next weekend,
Please let me know if you cannot come,
Your best friend.
