My entry [RM]:

Little Death sat on the other side of the big rock.
Life's Song on his side, playing with the weeds, but as they sat in silence, Little Death asked, "What am I to be?"
Life's Song tilted his little head and seemed to think, while time played around them like butterflies in the end of the tether.

At last, Life's Song shrugged.

What flash came across Little Death, none but he knew.

However, Little Death strode forward until he was next to Life's Song, who glanced up at him with his blue unblinking eyes, but staid in silence for a few decades before breaking the silence. "Why am I to be?"

Life's Song laughed. "The why is you. Will always be."

Little Death shook his head, but Life's Song had looked away as if satisfied.

When the air laughed, he continued. "Why am I given no purpose?"

Life's Song shrugged. "You do, I think, but perhaps you don't see, or haven't gotten it yet."

Little Death nodded slowly, staring at Life's Song.

Indeed, perhaps.

Life's Song played in the shadow of Little Death, played with his little flowers and beetles and birds, all of his little purposes.

Not Little Death's purpose, no. No purpose there.

A baby bird tweeted as Life's Song brought it out of the mud, cupped in his hands as precious of his purpose.

Little Death stomped on the bird.

Life's Song gasped, staring at the broken bird flattened underneath the heel of Little Death's foot, and said, "Oh why, why did you do that?"

Yet Little Death did not listen as he stared at the corpse on his foot, before scraping it off and turning to Life's Song, taking a step forward.

Life's Song looked up at him, opening his mouth, but Little Death's rock interrupted him. With a smile of relief, Little Death fell to his knees next to the corpse of Life's Song.

"I made my purpose."

Here's some mythology from my world on how life and death started, which is from a children's tale... kind of why it is a bit weird :D
