Dear Mike,
This Saturday is my birthday and my parents will hold a simple celebrating party for me. I am glad to invite you to come to the party.
Blair, Emma and Roan will also be invited. I am sure we will have a good time. We will have dinner at 18:30 so that you are wished to come at 18:15.
My mother is a good cook and you will enjoy the dishes. After the dinner, we will play some small games and then eat the cake. My parents and I sincerely expect you to come and hope to see you then.
True yours,
Daniel
