Repel boarders!

This morning Margie was unresponsive. I rolled her to the living room-day room that is large, tasteful, many easy chairs, and Margie looked around again and again with the same look as she used to look over our home we designed and had built, and asked, whose house is this? She usually welcomes my holding her hands, but today intertwined her fingers as if to repel boarders. Deeply saddening.
