Wow! So Granny basically disowned and treated as DEAD her own flesh and blood children, because they wouldn't submit to "WatchTower's" self-appointed authority and Lordship.
Sounds like Granny is reaping what she's sown. I'm shocked if ANY of her still-living children would stop by at all, after treatment like that!
If I got a call after DECADES of abandonment from my parents wanting to reconnect before their deaths, I'd tell them to seek comfort from their "Spiritual Family" now...ya know.....the Elduhzzzzz......because after all, "Jehovah Provides!" I'd then tell them to "keep warm and well fed", and then promptly hang up. I wouldn't want to disappoint them after all, being "Worldly" and a spawn of Satan.
