Dear Truc,
Some of our classmates and I had decided to host a small party as we had finished the semester with good grades, so I hope you will spend a little time to join us. This is going to be a very special party as everyone will participate in the making of it. Our teacher agreed us to take a part of the class fund to make the decoration as well as some other stuff, and every single member will take care of the food. It means that the party will include food from all the members of our class, and you can feel free to bring anything which is available. If you do not know which food to bring, it is fine to bring some drinks or fruits. This is going to be a warm meeting between our classmates, so it is no need to be stressed out about the food. The party will be held at 6pm next Sunday, and it would be nice if you have a little time to help finish the rest of the decoration. If you have any free time, please contact me so we can arrange our time to prepare for the party. If you need any confirmation from our teacher to show your parents, you can also call me so I can get one for you. I hope you will have time for this event as it maybe the last chance for all of us to gather and have fun.
Please think about this and make a decision as soon as possible.
I am looking forward to hearing from you soon.
Your friend,
Nha.
