Hello and welcome, Wonder*woman!
I'm a non-jw with some family in. I'm also "bad association" because I failed to progress with my "Bible" study.
I wonder if your sister was prompted by the horrible July WT article about apostates.
I've slowly learned that there is no reasoning with beleiving jws, and no compromising either. The only hope is to connect when they are in "soft" mode, have a good time together, and just wait out the times they need to toe the wt line.
I'm so glad your mother rang you, and hope she keeps in touch.
All the best, Retro.
