The Greatest of Waves

I did a cannonball into your heart
But the splash was too awesome, we drifted apart
I went down a river that brought cold to my bones
Wound up in the ocean so sad and alone
But I think it was worth it, when you wasted my time,
Spent all my money and ruined my life
Cause I'm dry and I'm happy back here on the land
I am building a castle, even though it's just sand
And I'm standing atop it, just waiting around
For the greatest of waves to come tear it all down
So now if you see me, alone on the shore
Know I've never stopped building but I'm tired and sore
For the wave I've been longing, it doesn't exist
The water's too distant, my castle gets missed
So I wait for a cannonball, with waves wild and free
That will tear down my castle and wash it to sea
