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.
