Unless you have worked with people in long term care that have massive insults to their brain...shut up.You may have your opinion but it is an emotional one,not an informed one.I have taken care of children with no brain,just a brain stem.You could hold a flash light near their skull and see light on the other side.These kids cried,blinked,had eye and body movement,appeared to sleep and to the uninformed they looked normal.Yet nature played a cruel trick and left them without the part that gives us personality and makes us who we are.She is the same.We see what we want to see and the most unselfish thing to do is let her go.People do not want to go throught the grieving process and hang on to every little thing.Her parents need to make the most magnanimous unselfish decision they may ever make and let her go.That is the true sign of unending love.Loving her enough to let her go.
