Great story. Keep us posted on what happens next. In my early days as a JW I would appoach people and confront them when I overheard them speaking bad about the Watchtower. One day a person at work offered me book to read. I think it was A Slave of the Watchtower for 20 (or 30) Years. For some reason I wasn't feeling quite as smug so I took it and read it. Nothing happened right away but it raised some doubts that continued to grow. You never really know what effect you are having on someone because it doesn't always show or it can take time for them to think things through.
Glad I continued to read this thread.
