My mom was served some regular coffee instead of her usual decaf today. Unless you've seen it for yourself you have no idea how strangely a wired nonagenarian with no short-term memory can behave. In addition to making her hyper, it has increased her sensitivity to all the various aches and pains with which she is normally afflicted, leaving her even fussier than usual. The only upside will be if, when the caffeine wears off in an hour or two, she then sleeps through the rest of the night from exhaustion.
My left knee has started catching when I walk and feels as though it might go out from under me. If I do a faceplant tonight that will be why. If I'm immobilized by it they probably won't find me until tomorrow morning. I hope I at least faceplant in front of the television so I'll have something to watch, assuming I can roll into the right position.
