I dated a sister back in the early 80's from a different circuit and her congregation was really into the whole study with the elderly found in nursing homes thing. .
One day we were out in service and the three of us went to the local nursing home to visit my friends "study" a 90 year old woman.
When she saw me she stood up, and grabbed my arm,,,, wouldn't let go. Everyone was flabbergasted, because she was never that excited to see anyone.
Well we soon found out why. According to her I was a spitting image of her long dead husband.
It was a little weird walking around the home with her hanging onto me. needless to say there was no study that day !
These days I have a therapy dog,, the elderly really seem to like that much more than reading the wt literature !
