Dear My
We're having birthday party for my younger brother Tuan this Monday evening. My family woul like to invite you to join us.
The party will take place at 8:45 p.m at my house (My Duc Apartment Building). We plan to invite some of our friends that you've already known. I hope we will have a good time together. Please come to join the singing and dancing activities with us. Of course there will be lots of food and drink such as cakes, candies and fruit juices.
I will be very happy if you can come, My.
Your friend,
Thao
