范文：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.
