Dear teacher,

There is a small party of my family this weekend. We respectfully invite you to join in the party with us if you like. The party is on Sunday afternoon. The party will start at 4 o'clock. The party is held to congratulate my progress this year as I made a lot of progress during the year. You can also bring your daughter - my classmate to the party, it's must be really great if she can join in with me. I hope to have your presence at the party.

  You student.

Dear Lan,

 I am very happy to send you my birthday invitation.  This birthday will take place next Saturday night, March 17th, and everyone in our class will be present.  This will be a themed party, where people dress up as characters from fairy tales like princes and princesses, and I hope you find this idea interesting.  The party will start at 6pm, but I hope you can come a little early so we can help finish each other's outfits.

 Feel free to contact me if there is any change or inconvenience

 I look forward to hearing from you soon

 Sincerely

 Mai
