The wind stirs the boats in the harbour. A gentle clanging as ropes bang against mast, rocked by the waves. The fishing fleet is out in the bay. All seems serene. Yet blown on the wind comes a raucous sound. The other side of the sea wall, the tide runs straight up to the rocks. Where the river runs into the sea. There the gulls are gathering. Not floating serenely, but in a frenzy of excitement. Here, where bitter salt meets sweet water, life explodes into being.
