Mom actually took my advice about calling the doctor, and the doctor told her to come in, so she was getting ready for that as I started to get ready for my day. I have a 1:00 p.m. appointment, but no other firm plans. I may well get another editing job.
Later: The nurse practitioner that Mom saw said that her foot was fine. I made it to my appointment. I was a bit late because I used white vinegar and water to clean sap off of the parts of the windshield that I could reach. That wasn't a problem.
After I got home, I watered the potted plants that are outside.
