Now, she is quiet and doesn't want to talk to anyone else. Her teacher said things are going backward in her study. ,F: Her parents must be very anxious about her. ,M: No, not really. Both of them are too busy to worry about their daughter. I think I need to talk to them and ask them to spend more time with Helen. ,F: Take it easy. It is something natural.
