The Shoes that were Danced to Pieces

Also known as "The Twelve Dancing Princesses," this has always been a favorite fairy tale of mine.

"Then they went all the way down, and when they were at the bottom they were standing in a wonderfully pretty avenue of trees, all the leaves of which were of silver, and shone and glistened. The soldier thought, "I must carry a token away with me," and broke off a twig from one of them, on which the tree cracked with a loud report. The youngest cried out again, "Something is wrong, did you hear the crack?""
