Then there were elders who "shared" info with elders from other congregations who would have one chatty elder who would tell his wife.
That's just it, there are plenty of elders who can keep there mouth shut.
It only takes a few with big mouths to keep the rumer mill going.
I married into a big gossipy family with multiple elders in multiple halls.
They freely shared JC details with each other.
Even as a true believer i thought there behavior was outrageous. It would really annoy me when the bros would give talks about not gossiping and they would usually direct it at the women. In my area the bros were the worst gossips of all.
