I have to use a cane to keep pressure off my leg and back. My first cane likes to play tricks and hide, so to be sure I always have a cane, I have 3 canes. Cane number #1 is my favorite. Cane #2 and cane #3 are backups and as I write this, cane #1 has gone missing. So I am using cane #2. And of course cane #3 is my safety valve. But I'm not buying another cane, #4, because I think cane #1 is just waiting for me to buy it so he can come out from wherever the hell she is hiding.
