I see your point Black Sheep, for those involved in mind control. But I also see it from the other side. When my son and his ex split, (a state away) my husband and I never really got to have any contact with our Grandson and Granddaughter, who were quite young. I continued to do the Grandma thing-- I sent birthday presents, Christmas presents, Easter baskets, Halloween candy, while wondering the entire time if the kids actually received them. Phone numbers never worked for them, and in 9 years time, I never even received any pictures of them. Totally heart breaking! We could have fought for rights I suppose, but feared that would make things more difficult in the long run for our son. We just hoped that some day things would turn around.
Fast forward to this last summer, the kids are now 10 and 11. Their worthless Mother was arrested for a dealing drugs. The state took the kids away from her. They told state workers that they had Grandparents in Nevada who sent them things. :) (they did get them) Their state tracked us down, and after all the paperwork etc was done, we now have custody of them! It was difficult in the begining, after all, they didn't know us, and we didn't know them. But there was an unspoken bond between us as we were family.
Now the shoe is on the other foot. However, unlike her, I allow her to be in contact with them. I don't trash their Mother in front of them either, I think they see it for themselves anyway! For the first time in their lives, they have a good stable life. After the last visit she had with them, the 11 year old asked me if I thought they would ever live with their Mom again. I told her I didn't know the answer to that question, and asked her what she thought. After a minute, she said that she loved her Mom, but that she wanted to stay here and live with me and Grandpa! :)
