Mrs. Wilson,
I'm going out shopping, and won't be back until about 5:00 pm. I have taken with me the two books you asked me to return to the City Library. At about 1 o'clock this afternoon, Tracy called, saying that she couldn't meet you at Bolton Coffee tomorrow morning as she has something important to attend to. She felt very sorry about that, but said that you could set some other time for the meeting. She wanted you to call her back as soon as you are home. She has already told Susan about this change.
Yours,
Li Hua
