I've never understood the rolling up of the trouser leg thing although it is very common in the nursing home. I started off wondering if the women were more used to skirts so when they were wearing trousers it seemed odd, so they roll then up so their lower legs are open to the air but I now know it's equally common in men.
One lady said as her husband was a former PE teacher and footballer then he was more used to shorts so she thought he was recreating his normal, another used to be a postman and a lot of them wear shorts. Is it correct or just trying to explain the unexplainable? Who knows.
The rubbing hands and legs seems pretty common too, one ladies habit is spitting on her hands then rubbing them together then when the fancy takes her wiping them on anyone handy.
It always surprises me that so many people who were so different previously in their life adopt so many of the same patterns of strange behaviour with AZ.
The ones I really feel for are the ones that pick at themselves, I've seen people pick at their (usually) arm until they bleed for no apparent reason, it's awful to watch and nothing the staff can do to make them stop.
