Bright sun
I was driving along a country road on a lovely sunny day when I saw an elderly gentleman walking on the footpath in the opposite direction. He was holding his hand above his eyes to shield them from the very bright sun. We were at least a mile from the nearest house so he was quite clearly going to be struggling to see for some distance ...... so I did 2 U turns to bring myself back to him and stopped alongside him and gave him my baseball cap. He was amazed that I would do something so kind. He was really grateful and offered to pay for the cap, but I said no and told him it was a gift. As we parted I saw him walking off with a smile and a renewed vitality.
