The saddest case of a return to the J.W's that I know of happened about 5 years ago. A young man who was gay had left and set up home with a guy he had fallen in love with.
He had been a Reg. Pio. and served in Bethel for a number of years.
What happened I do not know, but obviously the relationship failed, probably because the lad I knew felt so guilty that it just wouldn't work.
He worked at a return, and got re-instated. But we all know he will never be happy, so sad.
