Thanks Gary, this is a subject near and dear to my heart. Having been a member of the servant body 16 of my 24 years in the borg whenever I was transfered to a new Hall one of the first things I did was figure out who had loose lips. I would get close to them so I could get, "plugged in" right away but I would never tell them anything they could stab me in the back with. I did get fooled a few times and this did lead to me seeing how full-of-unholy crap the whole lot of them were!
My current GF is a pretent JW and she routinely tests the Nit-Witnesses by telling people BS to see where it will go. She told me she did that to me and I passed. Funny thing is it drives her crazy now cause I won't reveal surprises no matter how much she tries to goat me.
I wonder if that was part of why I never really felt like I fit in, I kept my mouth shut and, if I was the senior servant present, would give the friends a warning if we were in a group and the gossip started. If I was not the highest ranking male there I would watch and see how my superior handled himself. Never in 24 years did I observe a fellow Elder or Servant resist jumping in to the gossip fray.
