One pair of black shoes for everyday use.
One pair of black shoes as emergency spare in case the other pair become unusable. Imagine having to go shopping for a pair of shoes in my slippers.
One pair of slippers for everyday use.
One pair of slippers to take to the hospital with me if ever I am called upon to go. I haven’t had to go to stay for a few years now so the magic of the spare slippers is working.

I have a Zulu ‘juju elephant stick’ that works in a similar manner. Ever since I brought it home for South Africa I have been free of marauding elephants trampling through my garden.
