Dad's been in the hospital since Wednesday night (he fell and was on the floor a long time, which is not good for the elderly, and then it turned out he had an infection, which is probably what caused him to fall). I've spent most of my waking hours since then with him at the hospital. Today I think he's heading off for rehab-- he lives alone, and we have to get him able to get around on his own again before he can be entirely discharged. He's a stubborn old coot, and will probably do just fine with his physical therapy despite his advanced years. I do hope so, anyway!
