Much later: I got to work to find that B. had called me twice earlier in the morning to say that he'd messed the bed, and could I come to work early. I told him I hadn't checked my phone before I left for B. and R.'s place. He said, "Well, that's nice." Cleanup took a couple of hours. R. was having his own issues, but told the visiting nurse who changes his catheter all about it. She also looked at B.'s back, and said it looked better, ironically enough. I had been washing it well before I put the anti-fungal lotion on all along, and his back got an especially good washing today. I put the ointment in Miss Daisy's ears. I stopped at the nearby grocery store afterwards and got a rotisserie chicken for them and yogurt for myself, and dropped the chicken off.
Once I was free, I went to Walmart and picked up some things there. Then I came home and chilled.
