What if in the last 16 years Teri became wiser and now wants to live? Why should a stupid decision made years ago when she was a teenage know it all and had no understanding of disability have more weight that what she feels now?
She may be dain bramaged, but she is not as stupid as she once was...
Well, my short answer would be that if she now has an opinion one way or the other then she is not in a vegetative state and the question is moot.
