Scary weekend. Dad in the hospital because "he's not responding." That was Friday night. As of yesterday he's alert and communicating. Bad combo of an infection and dehydration. Worries me that he can be brought so quickly to the edge of the cliff when things go wrong. I think he's going to be okay this time. (Maybe why he didn't recognize me so well last weekend? Wonder if he had the infection brewing, they tend to make him a bit loopy).
