One of the most bizarre things I ever heard was a comment that surely Jehovah will "erase all memory of our non JW and DFed loved ones after they are destroyed at armageddon. That way we won't have to be sad over them and can truly enjoy living in the paradise earth."
At first I thought that this was just a nonsensical rant by a deluded fool, but later I determined that quite a few of the JWs believe this way and say this to each other.
(I came across this in a letter to my Dad written to him by another JW as I was going through his papers after his death. They were talking about me. It really upset me since I had been his sole care and comfort-giver for his last days on this earth. The PO had made one brief vist to pray or something and of course I had to leave the room.)
This is more than annoying--it's evil!
