Engine off. Clamber down to the beach. Vast white sand; Dangerous, beautiful, calming violent sea. I realise nobody - nothing - needs me right now. I'm free to do as I please. Apart from the phone in my pocket beckoning me back to the busy bustling world beyond. A quick check: no signal Power off. And with it, the heavy weight of all of life's responsibilities hidden away in a cluster of microchips, circuits and plastic - out of sight in my backpack. In go the car keys and the wallet too. No need for those here. Just you, me and the gentle hum of the sea as it sprays and sprawls the Scottish shoreline.
