Answer:
What goes in the water red, and comes out black?
I am never quite what I appear to be. Straight-forward I seem, but it's only skin deep. For mystery most often lies beneath my simple speech. Sharpen your wits, open your eyes, look beyond my exteriors, read me backwards, forwards, upside down. Think and answer the question...
What comes once in a minute, twice in a moment, but never in a thousand years?
Look into my face and I'm everybody. Scratch my back and I'm nobody.
Of no use to one, Bliss to two. Men lie for it. The baby’s right,
I’m grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
