I pretty much spent the entire day in the hospital today. From around 10 am to 1030 pm. Stayed with Dad, making sure he was comfortable. He was awake for a good part of the time, and I brought him up to date with general stuff about the kids and the rest of the family. The day passed pretty quickly, with dad drifting off to sleep every now and then. But his body seemed to have gotten its regular schedule back and he was sleepy when I left him in the evening.
In a nutshell, his doctors (who I met in the course of the day) said that Dad still had some infection in his body from the pneumonia, but his numbers were improving with each day.
