On another note about fading. Should you start your fade successfully slowly, it may work just fine for a long time. Suddenly the boundaries change and your former congregation forwards your publishing cards to your new assigned congregation. The elders there will suddenly come hounding you with drop in visits seeing you are now irregular/inactive and not going to meetings.
This is one thing that is unfortunately out of ones' control and the process has of slowly fading starts over again. It happens.
