That is what is so heartbreaking about this case. Terri surely didn't want the court battles and hatred between her husband and her parents.I feel the same way. No matter what else she did or didn't want, she couldn't have wanted this for any of them.
Except in circumstances where people don't get all of the necessary loved ones in the room to talk about the contents of the Living Will, which I would guess includes many people. I know I'm the executor of my parents' actual wills. I have no idea what the contents are.
But that was the point Jen was making, when she said to make sure you have your family sign the document, too. You get a big handful of your legal next-of-kin together, and make your wishes crystal clear, before it's an issue. If you can't get together physically, you talk it out on the phone, and write letters to confirm, cc'd to the other people.
My mother has made it quite clear to me what she wants. And I know, because we were together when my grandfather died, when my grandmother died, and when my father died. She's again made sure I wouldn't take extraordinary measures and she knows I won't. I know she doesn't want it. She's also made me promise to put her in a nursing home, if she can't take care of herself. I told her I couldn't promise, but that I understood it was okay with her, if I was ever in the position where her care became too much for me.
