To me coma means asleep with eyes shut and no reaction to anyone or anything. And even then, when my aunt was dying and in a coma, we sang happy birthday to her on her birthday and her hand started shaking and trembling. They did remove her feeding tube, but I think they had her on pain releavers. I know when my mother in law was dying of lupus they had her knocked out so she could die painlessly. They were unable to help either one of them. All we could do was try to let them die without pain, they were both very old and both had survived cancer and other problems over the years. But Terry, to me, is awake. Brain damaged, not brain dead. There is a difference.
I've seen the videos, and you're right, there's no way she's comatose. In fact, her responses are very much like those of my younger brother, who had very severe cerebral palsy and died of pneumonia a number of years ago. He literally couldn't do anything for himself; could only make noises (very much like Mrs. Schiavo) in response to questions, yet he could laugh, wink, and had normal intelligence. This whole affair is a travesty and makes me quite ill, especially with the knowledge that if this is allowed to continue the future may see us executing unwanted people by way of the cruelest means possible.
