Mrs. Wilson,
I’m going out shopping and won’t come back soon. I have taken with me the four book which you asked me return to the City Library. On about 1 o’clock this afternoon, your neighbor Tracy come to visit you. Looked worried, she said she couldn’t drink coffee with you this evening. She also said that her father were ill and that she would have to take care of him. She felt terrible sorry and promised to visit you before her father got better. By the way, she has already been told Susan and Grace about this change, so you needn’t call themselves.
Yours
Liu Mei
