| Dear David, Thank you for your letter. You want to know about my family and what they like to do on weekends. Let me tell you now. There are four people in my family. They are my father Mr. King, my mother Mrs. King, my brother Tony and myself. On Saturday, my father often goes to see my grandmother. My mother goes to work. She is a shop assistant. My brother often plays tennis with his friends. I go to the library. On Sunday, my father often goes to the chess club, and my mother cleans the house at home. My brother usually does his homework, and I go to the movies with my friends. Please write me and tell me about your family. Yours, Rose | |||||||||||||||
