My family was victim to this.
We were in the midst of an unintentional slow fade. My work schedule was the main contributing factor to our low meeting attendance. Having to work 2 to 3 double shifts on the weekend to make ends meet killed our field service participation.
We attended a one-day special assembly, which I had to trade and work a double shift just to attend, and I noticed that those whom my family associated with seemed rather distant. The big giveaway was after the afternoon session. Traditionally we always got an invite to go out to dinner. This time we didn't. In fact, all of our friends in the congregation were going to the same restaurant. No one invited us.
What gets me is the fact that the Watch Tower Society thinks this shunning garbage works as a pre-emptive way to get members to change. On the contrary; that was the finally nail in the coffin for my wife, who was not a born-in. I started down the road of an intentional fade from that point forward.
