So, feeling guilty, I skipped the gym, though I did walk home rapidly, enough to raise my heart rate; then I bought a new broom and a new scrub thing for the shower, and got some groceries, and then went home and cleaned my bathroom floor and got the beginnings of some mildew out of the shower.
I don't know if I really feel better, but at least my bathroom floor is cleaner.
I was reading an X-Men fanfic, which had promising scenes with Nightcrawler, but he soon vanished and it became all about other characters, so I stopped.
Am attempting to tidy up my e-book collection with Calibre. Still learning how to use it.
