John had another fall this afternoon while out with the dog. He was just round the corner, but out of sight. A neighbour came and alerted me, and by that time someone had already called an ambulance, so we've spent the afternoon at A&E. He's OK I think, another bump on the head, another black eye, another pair of glasses destroyed! They checked him over very thoroughly, patched up his grazes, and said he could go home. What got me was that the doctor told me to keep an eye on him and bring him straight back if he seemed confused.
