I bubble and laugh and spit water in your face. I am no lady, and I don't wear lace.
I am the outstretched fingers that seize and hold the wind. Wisdom flows from me in other hands. Upon me are sweet dreams dreamt, my merest touch brings laughter.

I have two bodies joined together as one. When standing still I run and run.
