Looking back there were quite a few families that did the "oh we're moving" fade. They would move to a rural area
or a state or two away. some would move clear across country. Then after some time no one would hear from them anymore.
It was always sister "busy body" that would say "oh I tried to get in contact with so n so...i think they stop going to the hall".
That happens when you move away from the congregation where people know you and can help you stay close to Jehovah"
