Heads or Tales

There once was a boy with a disappearing coin.
It shined like diamonds or faded like dust,
And so was his trust in reality.
He put his money into philosophy and lust
To find a deeper meaning in skin.
There once was a man with no past of his own
Who resembled a boy that had already grown,
He became magician, bought a coin for a trick,
Gave his trust to a boy, and disappeared sick.
