Sandcastle

I stand on the edge of my world and yours.
The two blend together on eternal shores.
Where one is receeding, the other advancing,
This dance of attrition, unwillingly dancing.

I don't have a choice, but it's much more than that,
I'm not given a chance to redeem in fact.
For in every attempt to create an existance
I'm drained of my life through your constant persistance.

Today you win, for I am undone,
I am no match for your powerful sum.
But in a few hours you'll weaken and flee,
And I'll be rebuilt, my army and me.
