I know of a sister in my former congregation who started partaking several years ago when she was about 40 years old. She is a die hard avid Bible reader and pioneer. All her conversations wherever she is at always ties in to the Bible. She is rather nice and pleasant. Still single though and moved to a foreign language congregation recently.
I wouldn't say that she fits into the typical JW mold per se, as she often gets into debate discussions about the scriptures with the elders and she often writes to the Society about scriptural matters. What develops from them, who knows? The elders pretty much stay clear from her. Perhaps of her extensive Bible, Greek and Hebrew abilities. She is quite independant, but respected at the same time. Personally, I liked her ways.
Nobody really started murmuring when she did start to partake. It was kind of a given when she did.
Holy spirit bears witness? I suppose so.
