Dear John,

I’m having Mike and Betty at my home for dinner on Saturday, October 5th. I hope that you can come. We are going to show the film "Walking in the Clouds" after dinner. I’m sure you will be very interested in it.

Dinner is at 6:30. We’ll be looking forward to seeing you at that time.

Li ming
