Weirdest thing...

I've got towels down on several of the chairs that Mom sits on because of the spontaneous piddling accidents we had a couple of months ago. Recently Mom has taken to picking up the towels (which are light yellow by the way), holding them in front of her face, tracing things on the towel in a line with her finger, and 'reads' the towel and says it has our names written on the towel. She'll do the same thing in the car, and in a church pew, 'see it says right here Tom and Mary Lou'. Mom's reading cloth, plastic, and wood.
