Dear Tien- Tien ,
How are you? Have you made any plans for The winter vacation yet? I have been thinking of Going to the east coast and staying in Hualien for two days. How about joining me? We could Make it an around-the-island tour. If time is Short, we could fly down to Hualien and then Take the train back along the eastern coast. There Will be lots of beautiful scenic spots for pictures! Give me a call or write me a note as soon as you decide. Yours affectionately,
Inviting Friends to a Birthday Party
Next Friday, September the fifth, is Tom's birthday. I thought it would be pleasant to have some of his friends here to help him celebrate. Will you come? We'll have dancing from nine until midnight, and then cut the birthday cake!
Both Tom and I are very eager to have you here, so don't disappoint us!

Apology for being unable to accept the invitation
Dear Li Hua,
I'm so sorry I can't come to Tom's birthday party. These days my mother has been falling ill, so I have to attend to her.
Thank you for asking me, Li Hua. I certainly hate to miss any of your parties. They're always such fun!
总的来说，便条可分为两种：请假条(note asking for leave)和留言条(message note left)。
