Lily is a student. She studies in No.1 Middle School. She takes care of everything carefully in her class. Her home is not far from her school. She goes to school on foot every day. It was cloudy and blowing hard last night when she was ready to go to bed. Suddenly she remembered that the windows of the classroom were not closed. She put on her coat and ran to school to close them. When she got back home, it was already 11:00 in the night. She was very happy thought she felt a little tired.
