Thanks for the update, Shirley. They all remain in my prayers, for comfort and strength to face each day.
While you all are changing your own smoke detector batteries, buy a 2 or 4-pack, and take the extra batteries to the home of a friend who might not be able to change his/her own. We do this twice a year with our wonderful neighbor, who is in her 80's; she's still handy with a chain saw on firewood, but not too comfortable on a stepstool!
