How it is, that a winter weekend city walk, can end up like this - by the seaside! How an inner city landscape, with its roads and concrete valleys between misty mid-distance skyscrapers, can be faded from consciousness by simply hopping over one, very long, brick wall.

So up and over the flood wall you go, with its curved brick top, and down you drop, not onto but into, something else. Something else entirely. Beach!

Yes a beach. A real beach! A wild watery foreshore, with blustery winds, and rushing white horses, and liberating rejuvenating scrunchy shingle under foot. You walk, over the unsteady ground, with a rolling swagger. You walk, right up to the water's edge, right into its bright white noise, its refreshing spray.

And everything, from only moments ago, is suddenly forgotten. Forgotten because now you remember. Remember what it is you are living for. This! Children playing amongst bright ringing stones. The thrum of deep channel cruisers. An accidentally discovered beach, beside the Thames, at Rotherhithe. Tidal breakers. Winter beach.
