Our two-and-a-bit year old granddaughter has become used to seeing me with my arm in a sling. After eight weeks it has become a normal part of her world. She recites its history and rules of engagement: "Arrow break arm. Doctor fix arm. Arm very hurt. No bang Arrow arm."
Last week was the first time she saw me take it out of the sling to do some of the prescribed physio exercises. She stopped dead in her tracks, looked very worried, pointed to the sling and ordered, "Arrow, put hand in!"
