Mother counts everything. Cereal on her spoon, squares of toilet paper to tear off & how many times she uses it. How many times she pats the dog. Parked cars, semis and billboards along the freeway. Brushing her hair and her teeth.
I guess it helps keep her mind somewhat active. Life as her caretakers is nothing if not interesting and never boring. I've heard the horror stories of caretakers with difficult parent's. I guess we are lucky in that respect.
