Remember all those talks on the time of the end where they stressed "When it's harvest time, everyone is working" and "A farmer cannot plow even rows if he looks behind" and all the "end is soooooooo close" talks?
People can remain on high alert status only so long, then they must unclench the jaws, and rest from the stress.
I think this has happened. When they changed the generation teaching in 1995, because it was ludicrous to go on saying that the end would come before those who were born prior to 1914 had all died, people realized in their hearts that the WT was feeding them BS for many years. That they DO NOT know when the end will come.
All of this is too hard to overtly think about. That is why no one says the emperer has no clothes. They would have to admit they were duped. They just keep nodding, smiling, and trying to gain some normalcy in their lives, like going back to school or encouraging their young ones to go to college. On the inside, they realize that they may live on this earth, will all its faults, for a long time...and they will have to face death, unlike the opposite pablum they've been fed from the WTS.
