     A teenage girl couldn't stand her parents' family rules, so she left home.

     She wanted to be famous. But she had poor education and several years later she had to ask for food on the

street for a living. Now her father has died. Her mother is an old woman. But she is still looking for her daughter. She has been to every corner of the city. Everywhere she goes, she puts up a big photo of herself on the wall.

At the lower part of the photo she writes, "I still love you..., come back home!"

     One day, the daughter saw one of the photos. The face was familiar. "Is that my mother?" she moved

closer and read the words "I still love you..."She cried. When she got home, it was early morning. She

knocked on the door. The door opened itself. She rushed to her mother's bedroom. Her mother was sleeping.

She woke her mother up,"It's me! Your daughter is back home!" The mother and daughter held each other, full

of happy tears. The daughter asked,"Why is the door not locked? A thief could get in."The mother answered

softly,"The door has never been locked since you left."

     The door of parents' love for their children will never be closed.
