Today it was SLOTH.
I couldn't get myself in gear, even low. When I was a kid the family had an old Packard, 1930 model, that had a low-low gear. We called it "granny low", and the old straight-eight cylinders in granny low could have pulled a box car up Tehachapi Pass. But it was s-l-o-w.
Today I couldn't even get myself in slow, old, granny low. I went back to bed and ignored breakfast. Well, it is lunch time, and maybe the afternoon will be better.
After my nap, that is.
