Some of these are not really WTF moments, more remarkable or sweet, but nevertheless a great and entertaining thread. I love the lady who arrived at the Swiss care home thinking she was at a historic castle.
Just thought of another one. I used to commute to work really early down the country lanes and into town before the roads became really busy with rush-hour. I did this for a number of years and one summer two really unusual things occurred.
One morning had the promise of a hot day to come and I drove through the quiet suburbs at 6am, window down, smelling the fresh air and blossom, when ahead of me was an elderly gentleman, around late 70's, slim, fit and supple as a 30 year old, roller skating down the centre of the left-hand lane, with shorts, knee pads, elbow pads and helmet. I saw him a few times that summer and after making some enquiries I learned his name was Edward, retired but still going back in odd days to do the family payroll.
The second occasion was taking a stroll out to buy some lunch. On a tree-lined avenue, was a parked estate car, with a rear door open and the boot up too. It was a hot day and as I walked by I could see the rear of the vehicle was kitted out with a mattress, drums of water, food and some low shelving. Clearly the home now for this man. He was sitting up, with an accordion, playing and singing along to sea shanties looking very much like a retired and homeless seaman, which I assumed he was. I always wonder what happened to him.
