Dear Tom Cruise, first of all, thank you for inviting me to your birthday party on January 1st. I am willing to accept your warm invitation, but due to the appointment two weeks ago, I can't attend. I have an appointment with one of my high school classmates.
He will accompany his mother suffering from cancer to see a doctor in Beijing. Because he is a stranger in Beijing, he asked me for help, and I agreed. No matter what, I'm sorry for your disappointment, but please wait for my surprise on your birthday I sincerely wish you a happy birthday, Li Ming.
Dear Clark, I'm writing to you. I'm sorry I can't go to the cinema with you on Saturday. My mother said she would take me to see my grandparents that day.
We'll make an appointment to see you another day. I'm sorry we didn't see you on time.
