A mother and her daughter lived in a village. Every night, the mother would lock the door with three locks,
because she was afraid that a thief might come in. As time went by, the daughter became tired of her boring life
there, and dreamed to go to the city to see the outside world. One day, she left home without telling her mother.
"Forget me, Mom," she thought.

and mind.
