Praying he is ok and his friend is a true friend. This can happen to anyone, such a shame when it happens in front of everyone. Any woman who has been caught out in her high heels knows how humiliated she is when you feel really smart and this happens. But you can't see anything on the floor. My boyfriend the first time we met in the 70's came on our first meeting in his cobbly wobblys and when walking on pavement it's like walking on ice. God bless our wonderful Guards.
Those streets get slippery after a rain. Im a blackfeet woman who has a british friend and he said the streets do get slippery where there is stone or bricks if wet.
