In the Brothers Grimm version, one of Cinderella’s evil stepsisters cuts off her toes, and the other her heel so they can both fit into the tiny glass slipper.
The prince is notified by little doves that there is blood on the shoe, and finally discovers that the true owner is Cinderella.
Once the stepsisters realize that they should try to win favor with Cinderella (after all, she will be queen), they attend her wedding, only to have their eyes pecked out by birds.
Did they deserve it?
I’ll let you decide, reader.
