I do have others that are less frivolous. There are two folding umbrellas in the car, one in the boot in a box of useful items - a first aid kit, matches, some shopping bags, a torch and a light weight shower proof jacket that folds into a pocket size packet and has more than paid for its original cost, while the other lives in the glove box for more immediate access.
Is this a little excessive? Probably. Am I going to get rid of any? Nope. Why not? Well, although I can't possibly use them all at once, I do use them and that's reason enough to hold on to them. In fact if I see another I like it may well come home with me. Just don't tell my husband.
