Crossing fingers, toes, eyes and nose that three days of rest bring you some relief from those (not so) blessed blisters. I'm also glad that you've found a way to make a real difference in the life of your "chap" and his wife. I've spent a fair amount of time with people who have Alzheimers and other forms of dementia, and their harried, stressed and overwhelmed family. Having someone come by, even for a few hours, can be a real life-saver for all concerned. I'm glad you're able to make a difference in their lives, and them in yours.
