Thanks for your reply Annie. Really helpful. It sure demonstrates that, some times, the negativity is not so much from the JW "branch" of the family, but the non-JW branch.
I certainly understand why non-JWs would want to avoid the JW influence at all costs, but when I think of some of my non-JW family members' insulting behaviour towards the JW family members, I kind of want to defend the JWs. There's never a good enough reason for people to be insulting and disrespectful towards each other.
Your sharing about the reunion with your sister is a testimony to your resilience and loving nature!
