This boy hand casting his line seemed to be either saluting or cursing the ocean.

Yin, Yang and the Sea

The sea strikes turquoise dissonance, then shhhsh’s it away,
releasing all the tension pent up by the day.
It speaks an easy language as it rolls along the bay,
but as often as it visits, we know it will not stay.

One by one, the waves roll in, devoid of parity.
They cannot seem to achieve any regularity.
With macho strokes of fury, they claw at rocks and beach,
gouging out in anger all that they can reach,
then turning female, lap the sand with gentle licks of tongue,
smoothing all the sand back that formerly it flung. 

The sea spreads riches on the beach, then takes them back again.
Theme after theme played out here in a continual spin.
Smoothing and then rippling, blue deepening to black,
all the sea might take away, one day it will bring back.
