WT is more concerned about losing contributing members,
how very true:
When my late father went into a care home--he ( in effect ) changed to a different congregation area. Quite quickly--he got visits from elders in his new cong. They all knew each other.
But he also had visits from an elder from the previous cong. Not unusual..but it agitated my dad..who was very frail and senile by then. Talking during my regular visits to my dad he said he was worried about his "obligation", and i worked out what he meant.
He had a standing order paying his old cong £100 a month !----but as i held power of attorney i had stopped that on his behalf LoL
