What kind of person tells his non JW granddaughter that the death of her infant son is a "sign of the times"?
A stupid, heartless @sshole, that's who. Witnesses have a very bizarre way of handling death. They like to give experiences of people who go out in Service the day after their loved ones have died, just to show how much "faith" they have. The truth is, these people are probably in shock and this is the only way they know how to deal with it.
I find it rather strange that Witnesses seem to think their view of what happens at death is somehow superior to what virtually everyone else believes. I mean, does anyone really find it "comforting" to "know" that their loved one is simply dead/asleep? I know when I lost a family member, I figured it would be A LOT more comforting to believe that their spirit was alive rather than be told they're dead and that's it.
They don't think you should "grieve" unnecessarily and that the best way to deal with it is by going out in Service even more, and make sure you're at all the meetings. Really quite sad.
