Grey rocks cover the beach, turning under my feet as I walk. Seaweed drapes elegantly over them, a friendly sea monster reaching out tendrils in greeting. Shells lie in nooks and crannies, wedged in place by the force of the waves. Hiding from the gulls. Shining copper brown catches my eye, stark in contrast. Basking in the late sun, the periwinkle nestles on its own boulder, waiting for the turning of the tide.
