When my father died, my JW ex and I were separated, but not yet divorced. I had been inactive for several years and she was aware that I had severe doubts about the organization. When the wake was held, she walked into the funeral home and proceeded to leave "Hope for the Dead" tracts around the room. She then began to berate me because I hadn't, as my father's only natural child, overridden my 4 step-siblings and insisted that a JW elder conduct the funeral. My father was nominally Protestant, and almost never went to church - not even Christmas and Easter. He was pretty liberal-minded when it came to religious beliefs, but disliked the JW's because they had sucked me into their cult when I was a teenager. I could easily have imagined him rising from his casket to object if his funeral were conducted by a JW. I tried to explain this to her, but of course, it was all about securing an infomercial for the Watchtower. When she wouldn't relent, I suggested that if anything ever happened to her, I'd make sure to get a Baptist minister to conduct her funeral. She eventually got huffy and stormed out of the building - a relief to all present.
I tell this story to point out that brainwashed JW's have no sense of propriety whatsoever when it comes to promoting their cult. Parties, funerals, whatever - it's all just another opportunity to get some brownie points with Jehovah.
