Answer:
When set loose I fly away. Never so cursed as when I go astray.
Sometimes black, sometimes white, I have veins but no blood
You can see nothing else, When you look in my face, I will look you in the eye, And I will never lie.
What looks back but cannot see?
Voiceless it cries, Wingless flutters, Toothless bites, Mouthless mutters. What is it?
A leathery snake, with a stinging bite. I'll stay coiled up, unless I must fight.
