Open Mike: The Effect of Adoption on Family Members

And what about impacts that may have come to us from those who went before us, or may continue on to affect others in the future? This is no stand-alone experience, to be sure. The affects are far-reaching - in time and in relationships.
I'm interested in your thoughts on this, so today's Open Mike question is:
How does adoption affect extended family members and friends?

Secondarily, my x's would certainly say it affected them, good friends tell me there is a frightening part of me that they don't have access too, that I withdraw for long periods of time, acquaintances find me guarded.
We were lucky because the couple who adopted her were family friends beforehand. In some ways it's like having another set of inlaws. I love her parents dearly and we are so grateful to them for their generosity in allowing us to be a part of her life. It is awkward sometimes, but in general, it's been very positive for us.
So from the point of view, I feel that DESTINY OF U IS FROM GOD!!! KK ok~ I guess I turned the head subject away >.<
