It is easy to tell when Cheryl is feeling good. She will start cleaning.
My go-to cleaning person is my niece, Natalie. She comes over for a couple hours every other week and dusts everything, mops floors, runs the vacuum.
I tease her about touching all my pictures and stuff. I do not watch her every move. I pick up all the towels and throw them in the washer.
But at other times, when Cheryl is feeling good she cleans for awhile. I suppose it makes her feel useful. When we were younger and she was without parkinson she would clean at random intervals. I think it was a calming mindless activity to her then and is a familiar activity now.
