Cinderella.

So, you have probably heard of the fairytale Cinderella. The evil stepmother, the ugly stepsisters, and losing her glass slipper. 
In this variation, The Hearth-Cat, there was a widowed schoolmistress with a plain young daughter. The daughter went home to ask her father to marry the schoolmistress, and he said if his daughter wore a pair of iron boots, when they rotted out, he would marry her. The mistress was pleased with this, and instructed her to wear them every day. One day, they started to fall to pieces. She told her father about it, and he married the mistress that day. When he was home, she was treated kindly. But when her stepmother was home, she was basically a child slave.
I think this relates to the original Cinderella to an extent, with the evil stepmother and being treated like a slave, having to do all of the house work. To me, the lesson is to not tell your father to marry your teacher. The same concept as our version- evil stepmother;and the father has no idea.
