Woke up around 5 AM and couldn't get back to sleep upstairs, so decided to sleep downstairs. Unfortunately, in the dark I missed the last step and my own step was longer and with a harder landing than expected. At the time, this didn't seem a big deal. Later, after waking at the right time it was a big deal as my right knee randomly sent me nasty reminders not to do that sort of thing. These reminders come in the form of pain or a strange "I'm bending now, never mind what you want" falter. At least I haven't actually fallen over. Most of the time it's fine, but I don't know when I'm going to get a reminder, so today I'm using a cane. When a cane is a prop or walking stick, it's not bad. When it becomes a necessity it makes me feel old. I expect I won't need to use it in a day or so.
Oh, the flashlights? On the nightstand that was by the bed there were not one but two portable light sources. Had I used one of them I'd not have missed that last step. D'oh!
