I have a friend. Her name is Mary. Mary’s daughter is a girl of ten. She goes to school. She usually comes home from school at three o`clock in the afternoon. She often helps her mother at home. Mary’s son does not live with his parents. Last year he graduated from the Institute and went to Kazan to work there.
