It was nobody's fault really -- it was just the wretched weather.
With all the recent snow, the pavements were an icy nightmare of accidents waiting to happen, and just such an accident was happening right in front of me.
A very, very attractive and well preserved lady walking in front of me slipped, and fell rather heavily and awkwardly, banging her head as she fell.
Hurrying up to her as quickly as it was safe to do so, I did my best to reassure both of us that she was as alright as she could be and not badly hurt. Having got her upright and sitting comfortably on a nearby low wall, I then did my best to find out if she was in a fit state both mentally and physically to continue on her own way under her own steam. It was when we were in the process of this verbal exploration that she suddenly burst into floods of agonisingly gut wrenching tears.
"Whatever is the matter?" I said, "Are you in pain? Does something suddenly hurt? If so, where is it and do you think I need to call an ambulance for you?"
"No, no" she replied, "I really am not hurt physically in the least, but my memory seems to have really... really horrible gaps in it! I mean I'm only 53 and it really shouldn't be playing these sorts of tricks on me... should it?"
Fifty three!
Good heavens I thought -- I had mentally put her down as a toothsome twenty years younger than that from her outward appearance, and her actual age came as quite a considerable shock to me.
As I continued to talk as calmly and soothingly to her as I could, the intensity of her sobs decreased slightly, but they still gave no signs of stopping.
Eventually as I ran out of platitudes and there, there's, I finally asked the question I should have asked in the first place.
