I am very glad that my mother is coming this afternoon by air. But I have to give a lecture and have no time to meet her. I am writing to ask you to meet my mother at the airport at 3:30 for me. As you have never seen her before, I will say something about her to help you recognize her. She is around sixty years old, fat and short, with a long face and gray hair. I have been told she is dressed in a white blouse and brown trousers and she will take a yellow suitcase with her.
I will be thankful to you for your help
