Fairy Tales

As a child I loved fairy tales, one of my very favorite was The Twelve Dancing Princesses. The story tells of 12 princesses who were locked in their room each night, but each morning their shoes were worn through as if they had danced all night. Their father, the King, is determined to find out what is going on and so the story goes. Other favorite fairy tales were, The Princess and the Pea, Rapunzel, Rumplestiltskin.
There is the secrecy aspect of the fairy tale, as in the dancing princesses story, the king had to devise a way to find out what was going on. Fate happened to be on his side as an old soldier returning from war had a chance meeting with an old woman who gave him a cloak of invisibilty and advised him on what to do.
There can be someone who is villainous, as in Rumplestiltskin, what kind of a mean person would demand someone's child, he needed to be found out.
There is a test to be endured, as in The Princess and The Pea. How else could the Prince have known that she was a real Princess without that pea. After all, sensory integration disorder had not been discovered back then. But maybe, in fact, Hans Christian Andersen had it and incorporated it into his story.
All I know is that fairy tales are magical and everything turns out right in the end.
