Tonight we arrived to find the nurses giving dad a lot of special attention during his evening meal. They were working hard to get him to interact with them and they were succeeding. He was answering questions and interacting but each response had to be pulled from him. This was actually an improvement over previous days.
As we spent more time here dad has drifted off into deep sleep. He occasionally seems like he is having a bad dream. Nothing to do but watch while he sleeps.
