Run..

Do you know me , who I am?
Have you seen me hunt?
I love to kill, I live for death
I laugh at your last breath.

I never grief, I am always glad.
Glad to take your life.

My teeth are long, my nails are strong.
And my heart as cold as stone
Try and melt it you might succeed,
With your blood.

You wouldn't have liked me
If you saw me I'm rather vile you know.
But I'll give you a little hint,if you see me, run!
