High tide on the River Crouch. Night. Not a soul about. Small bobbly waves gamboling along the brimming tideline. Playful, in swilling swirls, reaching for one more inch of land, before the ebb. From the east, a lazy wind muffles. 

 

Tide turned. The surface has begun to calm. Palmful waves bob over each other in glassy melodious slurps. Their thirst for land is over. Retreat not yet in mind, and still nudging the hard ground, they are letting themselves settle to its dry resistance. Night wind softly presses.   

 

The ebb. A grainy hiss of newly exposed land has appeared along the tideline. The water, relaxed, moving slow like a minute hand, is inching back. It's slackened, into tiny, feathery currents. This place is no longer about a shoreline. It's opened. Become panoramic. An aural vista. Wide, silent, tidal river. Far off, murmurs of nocturnal flying curlew, redshank, and geese. And of a low, soporific hum. A ship. In port. Docked, and sleeping.
