Hi Rosie, and all you good folk. It seems the argumentative behavior starts around 5:30, through 9:30 PM. A simple question will set him off. Tonight I asked if he wanted to spend the morning with his wife, at the nursing home (b/c I have to get winter tires on, and he hates to wait). Well, you would have thought I'd asked him if he wanted to go ballroom dancing. He shot back with "that's an awful thing to ask a guy, I hate waiting around, you know that," and on and on and on.
Gosh it takes a lot of patience to deal with this fellow at this stage.
So, before I do anything tomorrow, I'm going to make him a doctor's appointment. It will probably take a week or so to get in. They're always swamped. Also, I have to get him on the Alzheimer's registry. I'll let you know how the medical check-up works out.
