A good number of years ago I was sent to an exhibition in London for equipment research purposes and with it being lunch time I set off down a corridor duly marked.
Coming towards me on my side was a figure in a raincoat, I moved to the side to avoid him and he copied the action. I moved the other way for it to happen again. I then realized with something of a shock I was walking towards a full length mirror and was getting close to impact!
I just hadn’t recognised myself in unfamiliar circumstances despite having much better eyesight than I have now. Shame really, it would have been nice to have someone to chat to over lunch!
