I remember a similar story from my old hall, that happened many years ago. It was the same thing, some "sisters" saw a married brother out in public, including dinner, with a woman that wasn't his wife.
Mind you, the brother was in "good standing", but he was a nicer looking man, with a slightly less attractive wife. Looking back, i think it was that reason, as to why the gossip and assumption happened. In other words, this "brother" HAD to be cheating with another woman, cause he was just sooo nice looking, but his wife was just "average".
This ridiculous attitude led to the "sisters" going to the elders, and the elders approaching the "brother" about it.
WELL, guess what, the "other woman", was the brothers SISTER. She was visiting from out of town, and he was taking his fleshly sister for a tour of the city.
Needless to say, this action, judging, and ASSUMPTIONS, of those "evil" gossiping "sisters", REALLY stumbled this brother, and his poor wife. So much so, that they are no longer in the BORG, and havnt been for quite a few years.
So, this kind of shit, happens all the time in the borg, and it seems that it doesnt even matter if you are "active", in good standing, or "inactive". The gossiping, slander, and malice, is so prevalent in the Halls, its almost like they are a breeding ground for it.
