Riddle Poem by soren Barrett

I have no name, emerging from a sandy lair
Character without depth no shadow I cast
A child's game of peek-a-boo where I'm there in a silver stare
Knocked down by a baby's blow, another round I won't last

Born orphaned from an infertile mother
In a land where right is left and what was left is right
Twin with no sister or brother
Black back, face reflected light

With no teeth or mouth old women are afraid of me
No ears your secrets I keep
Looking into another I see eternity
Always standing I never sleep
