Argh. Today was supposed to be a relatively low-impact day, at least as far as my ankles and knees are concerned. Because they were already hurting like hell and swollen and unstable and generally not good. All I had to do today was office hours, and writing some quizzes and worksheets and prepping for classes tomorrow, and making copies.
So. I was going to make a lunch and bring it with me, but I forgot. So, I figure, I'll go to the convenience store in the building next to my office building and get something there. I walk (with my walker) down the very long hallway from my office to the elevator, get down to the lobby, get almost to the door of the lobby, and realize that I left my wallet in my office. So, back across the lobby, back up the elevator, back down the very long hall to my office -- and I realize that I got off the elevator on the wrong floor. So, back down that hallway again, up the elevator again, down the hallway on the right floor this time, get my wallet, back down the hallway to the elevator, etc. I finally ended up back at my desk with something to eat half an hour after I'd started. At least I remembered to buy some razors at the store while I was there, for a ridiculous price, but I need some and it's better than having to stop somewhere else on the way home.
And then the copying machine on my floor was broken, so I had to do the same stupid walk from my office to the elevator a couple more times to make copies using the machine on another floor.
And my knee keeps trying to bend sideways. It shouldn't do that.
