You know the feeling when your body quits?
Left the house before sunrise, and had to scrap extreme frost from the windshield. A busy day at work. Lots of errands to run on my way home. At my last stop (the library), I sat on the floor to peruse some options. I am a floor-sitter from way back. When finished, I just did not have the energy to get up. I sat there looking through a few books, until I had gathered enough to toddle out of the stacks.
I was tired and achy before, but my body rebelled, put it's metaphoric foot down. Another weather system passing through, taking the cold day to Polar Vortex through the end of the week.
