An extract of a poem by Stephen Crane, which inspired Stephen King whom adapted it to part of his earlier works, The Eyes of the Dragon. That book was one of my favourites.
The original lines went as follows:
"In the desert
I saw a creature, naked, bestial,
who, squatting upon the ground,
Held his heart in his hands,
And ate of it.
I said, "Is it good, friend?"
"It is bitter bitter," he answered;
"But I like it
Because it is bitter,
And because it is my heart."
So if you ask me how have I been, can I answer you, "It is bitter bitter? But I like it, because it is my life?"
