Watchtower Witnesses - "Another tactic is to play dumb, just ask them to explain some of their doctrine simply as if you don‘t fully understand it. It's possible while explaining some of their odd beliefs a little doubt will set in the back of their mind."

What a great, great idea. I think I accidentally did this as a child, I asked my mom when I was very young "In the new system if I fall off my bike, my arm won't break?" something along those lines... I vaguely remember her fumbling to answer but not being content with her response, and feeling she wasn't either.
It causes me so much fear and anxiety to bring up this topic with her, takes me right back to being that scared, abused, vulnerable little girl but I am going to suck it up and do it. I'm going to ask her questions, just listen, and let her come up with the silly reasoning, maybe causing her to do some research into it rather than just give a robotic response. It's worth a try. The worse that could happen would be that I'd give her hope I was "coming back around" but I refuse to feel guilty anymore. Guilt is what ran my childhood, my teenage years, my young adulthood. But I have strength now and I know there's nothing to feel guilty about.

If anybody has any further idea's about questions to ask that would get her thinking, please pass them on.
