She obviously is living in some world of her own where she gets to re-live her past through her children and then through her grandchildren.That's probably why she assisted Bruna in the kidnapping. Maybe that's where Bruna developed the ME syndrome too. It's all about ME and I want what's best for ME, and to hell with who ever else it affects.
It's interesting, when my Mom (who is from Brazil and is visiting) and I read the letter together, she said the following: "it seems the child was taken to fulfill HER needs, she was living away from her grandson and NEEDED to be next to him 24/7. I live far away from my grandson, I know that's not easy, I suffer too, but I'd never let you or push you towards her daughter's actions. In fact, if you showed up at my house and said 'I want a divorce, I'm staying here with my child' I'd say okay, you want a divorce? Let's go back, get you divorced, settle custody and go from there. I raise my daughters to be responsible and never to do something like that."
