I heard a somewhat amusing story from a co-worker over lunch. He said he was at a funeral for a JW relative, and they had a registry for guests to sign. His wife signed the registry, and included their home address. You can guess the rest. A couple of days later, a JW from the funeral showed up at their home with some literature, and offering a "hope" for the future.
The co-worker found it both strange and amusing. I just chuckled and said, "That sounds about right." I guess the moral of the story is never let JWs know where you live.
