There was a lovely fairy tale in my ex's Children's Classics, titled The Light Princess. All about a princess cursed from birth as having no gravity both emotional and physical. Meaning that she was buoyant in every sense of the word.

Her nurse had to tether her to the cot to keep her floating away as she pealed baby laughter. The story follows her growing up years where she discovered that in a nearby beloved lake, she had gravity. She could swim and feel her own weight. She loved the lake like nothing else.

A time came when it was time to marry the princess off, so the king announced that the man who could bring his daughter to tears would win her hand. Se saw all suitors off with laughter, no matter how sad their tales.

One day the wicked old aunt who had first cursed the princess annoyed at her blissfull happiness when she was swimming in the lake, decided to remove the stone stopper which kept the lake water from draining away. (There was an inscription on this stone - cannot remember it)

Anyway the princess fretting yet still unable to cry, charged one suitor to stand in the place where the water was draining away. He did so out of love for her and she would swim out to him and give him food and drink each day as the lake refilled. On the moment the water closed over his head, she realised she loved the young prince and burst into tears spell broken. He was rescued somehow and they .... yeah you guessed it lived sappily ever after.

Still it was a lovely fairy story. Wonder when Disney will discover it and ruin it.
