Sidewalk Seashore

Today tides welled on the sidewalk. 
Today I sat on the shore, the curb,
Today I watched the tides roll in. 

Paint floated the waves, 
White and yellow breakers;
The ants on their journey,
Fast drifting towards purpose. 

At sunset, shadows marked
The tideline; dark and light, definition,
Contrast and the slow shift,
A dune and roots that bind.

The wind, waves, light and night
These things move against the moving;
Roll into dunes that roll 
As waves wash off the daylight
And night rolls in with the moon –

As bright shells appear through waves of sky.
