I knew many. With all of the below-mentioned I had many a deep discussion about, and oftentimes in contradiction to the doctrines of, the WTS:
Brock was a good friend. He disappeared after his wife walked away.
Tom is still an elder, having survived similar family difficulties.
Alan was an elder till the day he died; he and I had many a discussion after the book-study that he held in his home.
Don is the former CO of a congregation in the Tri-county area, and he, though not what what might call an "intellectual" fellow, was a good friend, and we related on a deeper level, having been through many similar experiences.
Several CO's, each of whom (including some who stayed as guests in my home) had their own peculiar abilities to relate to my concerns, and two of which were instrumental in delaying (though not defeating) my df'ings for apostasy.
As an aside, I recently had opportunity to talk with one of my college instructors, and in the course of that conversation she mentioned that she had a couple of students who were JWs. I informed her that I too was a JW when I went to college, and she expressed considerable surprise. Her words: "Craig, you're one of the smartest people I've ever met; how could you have ever been part of such a religion?"
""Smarts"" has nothing to do with it (double quotes added deliberately).
