Maybe I am just sensitive, but I cannot abide umbrellas. The owners of this dubious fashion accessory seem incapable of understanding the damage that can be wrought with the rib ends to anyone's eyes let alone mine.
Umbrellas have a simple function to keep the rain off ones head and shoulders, so why, oh why, oh why do some people carry umbrellas that could house a circus. A golf umbrella is for the golf course not the city.
I am surprised that H&S of even the EU have not outlawed them yet.
I can only say that the morons who wield these dangerous weapons should at least be compelled to have insurance lest they injure anyone especially me!
Maybe this is the answer
