Its funny because i was just thinking along these same lines, the other day. My sister and i were raised in the "truth", so naturally, our close "family" became the friends at the congregation, NOT our real blood family.
My Father and Mother were the only ones who became JWs, and in turn raised us, but nobody else on my Mother or Fathers side, were JWs. My Father became an Elder when i was very young, so he jumped in head first.
Mind you, on both sides, my Mom and Dad, both came from large Italian American families. While my Father was an only child, he had tons of Aunts and Uncles, and cousins, and my Mom was one of 3, plus Aunts, Uncles, cousins. In theory, my sister and i should have had a HUGE extended family, from both sides. Instead, we were very rarely involved with our "worldly" family.
They were looked at, and thought of as being in the world, with nothing to offer us, and we were most likely looked at as the weird religious family of 4. Yes, over the years we saw certain family members here and there. We would visit my Aunt and first cousins in Florida during the summers here and there. My Grandmother would have her get togethers with family and we would be there.
That being said, there was always an unspoken wedge, of "Us and Them". We were the ones who didnt exchange presents. WE were the ones who didnt celebrate birthdays, and holidays. Looking back, you realize that all the extended family members probably didnt completely understand why, and different opinions could, and did form. Some might have thought my Father was cheap, for not buying his kids gifts, some that we were rude, some might have thought we were in a Cult, some might have thought my sister and I were being deprived, who knows, really.
I look back now and think, maybe these family members, that we were not allowed to get close to, because of the Cult, could have directed or impacted my life in ways i will now never know. Most of the family are older now, and have passed away. We just buried my Fathers last Aunt, which was the last sibling of my Grandmother, that was alive.
My Father, also, getting up there in age, has really seen the Borg for what it is, a CULT, and i think even now he realizes that years and moments were lost with family that WAS blood, and instead those years were given to a CULT ,and to people that PRETENDED to be family, but instead were conditionally there, as long as you looked the part, no true love.
Its a shame.
