This evening as I was leaning on my patio fence , throwing stale bread to my chickens ten feet below, the fence gave way. I had no chance to get my balance back and did a controlled leap, culminating in a superb knee, hip and shoulder roll, as taught to me on assault courses in 1984 basic training. Bouncing easily back onto my nearly fifty year old feet, I looked around to see if any of my neighbours or indeed my wife had seen my impressive performance. None had. The wife was in the kitchen, sorting the recycling, nobody saw it. A wasted effort. What great things have you done that no one saw?
