I remember the "she's my study" "no she's mine" battles. One got particularly ugly. An elderly sister - very genuine and kind but who would stand her ground - locked horns with a particularly unpleasant and sharp tongued elder's wife.
The elder (weak and lily-livered especially when it came to his wife) had the "book study" at his home and banned the elderly sister from going to the group there.
After several weeks of this the rest of the body - instead of removing the toady elder - moved the elderly sister to a different group.
The bad news is that the "study" that was fought over got baptised.
The good news is she has been inactive for over twenty years! And not too long afterwards the toady elder was removed by a circuit overseer when he heard about it.
