A MOST shocking thing happened to me as I strolled along a quiet West Devon lane on a recent sunny day. A sudden tinkling of a bell behind me caused me to nearly leap out of my skin with surprise. I turned to see a lady bicycle rider bearing down upon me and at once I realised she had rung her bell to politely warn me of her proximity. 'What an excellent idea,' I thought to myself as she passed me by with a cheery wave and a smile. Do you think this sort of thing might ever catch on? Keith Scrivener Sheepstor West Devon
