Gill, such a sad situation for you and your grandfather.
Seems that JW's are able to rationalize everything. He's "asleep" so he has no knowledge of who's there at his funeral or not...or even if he has a funeral. We'll all throw a big party when we greet him at the resurrection. Though, I must say that even if such a hope was true and your grandpa resurrected, I'd hardly think he'd be in charity with your aunt and those who swiped his money, interred him in a home, and hardly bothered to visit him in his final months.
It's sickening how many JW's discard relatives and friends when they become infirm and then have a sactimonious memorial service after to show what a loving and caring bunch they really are. What a crock.
