I just wanted to say thank you for all your replies. My family and I did attend the family reunion, and as the JW relatives had planned, showed up late, assuming that we would be gone by the time they arrived. One of them pulled my husband aside as asked for us to leave. My husband's reply to him was rolling his eyes, and said, "Yea, what ever. We'll leave when were good and ready, and not when you say so." There was an F bomb placed in there as well.
Anyways I did see the woman who use to be my biological sister there as well. But I made sure that I was totally ignoring her, I know that this would burn her to no end, because she was the one who is suppose to do the shunning. There was no love loss in the beginning, because I absolutely can not stand the site of her, even when back when I was still a JW.
The family reunion went off really well, and I got to see family members that I hadn't seen in years. I'm thinking that the relative that originally asked us to leave early in a message was only doing that, so to convince the JW relatives that we would not be there by the time they arrived. But it still ticked me off, her even bringing this up, but that's under the bridge now.
As far as doing any anti witnessing, I never had to do this, because most of the family (who are not JWs) have already seen first hand the ugly side to those people. Their actions towards us, back when we first left, acatually prevented several relatives from evening joining that cult. I did think it was pretty funny how my husband handled his brother though. He a very blunt man, and he doesn't care who he says it to, well except for me, because he doesn't want like seeing my red hair flair towards him. lol
