Mary Worth lived a long time ago. She was a very beautiful young girl. One day she had a terrible accident that left her face so disfigured that nobody would look at her. She had not been allowed to see her own reflection after this accident for fear that she would lose her mind. Before this, she had spent long hours admiring her beauty in her bedroom mirror.

One night, after everyone had gone to bed, unable to fight the curiousity any longer, she crept into a room that had a mirror. As soon as she saw her face, she broke down into terrible screams and sobs. It was at this moment that she was so heartbroken and wanted her old reflection back, that she walked into the mirror to find it, vowing to disfigure anybody that came looking for her in the mirror.

Another version:

A long time ago there was a little girl named Mary. She must have gotten in an accident because she went into a coma. At this time doctors didn't know what a coma was, so they thought she was dead. They buried her alive! Every night Mary's mother thought that she heard a scream coming from Mary's grave, but no one believed her.

Finally one day Mary's mother convinced them to dig up her grave. When they did, they found scratches on the top of the coffin and Mary's fingernails were all bloody.
