Shards of sail staple sky to sea as fingernail-thin boats lean in to the horizon.
The surge of surf converses constantly with the silent shore, urging its message upon the oblivious beach.
My children scramble on the man-made groyne, a facsimile of wild rock, in which they find caves 'with a proper rock on top' (Bea) and 'a hundred miles deep' (Willem).
We are here on bikes, salt wind in our hair, and my *** slowly absorbing moisture from the almost-dry sand as they unburden their youth upon the rocky playground.
And then come the treasures.
A flat shell the size of my palm and worn pearlescent smooth.
A fossil pebble of concentric ingrained ripples.
'Something amazing Mummy,' comes the cry. 'You have to see this stone; the colour of Coca Cola,' shouts my boy.
More treasures emerge and are grafted on to the sandy pile.
Quartz-like lumps and a mussel entangled with tiny seaweed strands and miniature white shells, like micro leaves and hints of feta in a fancy restaurant.
The boy wears welly boots, no socks, and a plastic medal around his neck. 'Batman, Batman, Batman,' comes the cry, while Bea determinedly scans heaven and Earth for jewels to stud her imagination.
