I don't know if this is a subtle policy change, or a non-official but people are just doing it policy change, but my sister, who is a devout JW, has been for decades, is a pioneer, etc., just this year sent me a birthday card that actually said "Happy Birthday to my Sister" on the front of it. Inside was a handwritten note about the bond we will always have as "Sisters".
This is a huge change from a few years ago when I received my first "birthday" greeting from her in decades in the form of a "For Your Special Day" card, no mention of birthday or "sister". She used to refer to me as her "fleshly sister" which bugged the heck out of me since it's an ugly term and implies I'm second class at best and soon to be birdfood. So this is progress.
She also sent a birthday card, which also said "Happy Birthday" on the front of it, to our father, with money enclosed for a gift, with the suggestion that he and our mother go out to dinner on her money. So, a card AND a gift.
As I said, I don't know if this is policy changing at individual level, or maybe that she herself is beginning to realize at last that all the crudola she has believed all these years is basically the same stuff that they bag for fertilizer. Whatever, I'm rejoicing in the change, and encouraging it.
I also never say word one against her religion, which I believe lowers her defenses since she expects everyone to oppose her. I just make a point of telling her a bit at a time how blessed our own lives have been because of our own religion. Apparently that has begun to hit home, too, as she included comments in the last conversation about how she knows it was my religion that helped bring our two adopted sons out of the nightmare trauma of their birth family. She actually said all the programs we have for children really helped our children (as opposed no doubt to how it is in her JW world where the children get zilch by way of child-level fun at church).
So she is recognizing that Sunday School is actually of value, and youth programs, even though not something done in Bible times. (Like anything about our lives can related directly to how they did things back then anyway!)
So maybe even the older ones are beginning to loosen up a bit. We can hope.
