Was your uncle terminally ill at the time? Terri was physically healthy. There's a big difference.
In fact he was not. Oh, there was not anything in writing either. He could not communicate with anyone. But knowing my uncle we all knew he would not want to be kept alive like this. He had a severe stroke a few years before that left him like this. At first he could communicate somewhat, but then as his brain athrophied it became clear that he was not ever going to speak to any of us again. This case has really brought it home for all of us who loved him. He was a wonderful delightful man and all of us miss him very much. But I also know he is with our Lord of whom we celebrate his resurection today.
more important-did he make his wishes known?
