OCD (Obsessive Compulsive Disorder) is not fun to observe. It involves repeating the same thing over and over again, repetitious and redundantly, ad infinitum.
Today it was "there are too many dishes. I can't do the dishes. It's too hard." Endlessly for 15 minutes before his PCA came.
Fortunately his PCA has an ability to get him moving. He's really good. Have I mentioned we like him?
