I know of a few JW friends who from time to time have to do a disappearing act from their hall.
One JW finds a "reason" to leave town to visit relatives and another JW would go to "visit" another hall in a nearby vicinity. In all honesty, they are fleeing from the strife in the kingdom hall when they are in the spotlight. From what I am told, the gossip is at monumental proportions and people are regularly shredded by troublemaking, gossiping sisters in the hall. Whether or not the elders know is one thing, but I don't think they care to do anything about it. I don't think the elders care one iota what the women in the religion have to put up with.
I am a ten-year "fader" and I have mentioned to one of these well-meaning JW friends (who imagines she will reactivate me) that I would never tolerate what she puts up with and it seems to be getting worse! Now that I am out, the whole thing seems so insane to me. How on earth could they possibly call this a brotherhood???
