Hi Joe,
We've found exactly the same thing. I still do work for some wittos from time to time and till now (we've been physically out since August last year) only one of the elderly women has asked when I'm coming back to meetings.
It used to perplex us. Now we see it as more of a blessing in disguise. People still wave to me in the street and say hello but no one can be arsed to pop round or have even tried to get us to come back.
The really ironic thing, as was already mentioned somewhat, is that I see them out in service all the time trying to recruit new drones but they don't care about the ones who leave. So much for genuine friends and Christian love.
