Dear Mike,
This Saturday is my birthday, and my parents are hosting a small celebration party for me. I would like to invite you to come to the party. Blair, Emma, and Roan will also be invited. I am sure we will have a wonderful time. We will have dinner at 18:30, so please arrive by 18:15. My mother is an excellent cook, and you will enjoy the dishes. After dinner, we will play some games and then have the cake. My parents and I sincerely hope you can come and look forward to seeing you then.
Sincerely, Daniel
