I’m walking (OK hobbling) home and laden with shopping when a football comes flying over a nearby garden wall. It arcs strategically about to land precisely at my feet. In my panic in trying to not let it bounce into the road besides me I instinctively swing my foot lightly up to stop the ball. A kind of Zapruda effect applied to random object occurs as the ball smack into my feet and ricochets right back along the same arc it came from without ever having touched the ground.
I hear the sound of surprised voices and a small child who say “Who was that?. Dad-type voice: “er..I dunno”. Me (clearly in a world of my own): “It was I, the masked passing footballer”.
I had turned the corner by then so for those on the other side of the wall the mystery remains.
