Amazing ... the videos from 1992 or 1993 show Terri clearly swallowing and licking her lips. Did you know that PVS people can't lick their lips because they don't feel anything to lick at and can't control such a rudimentary action? As for the smiling at her Mother's voice (she was proven to be blind to anythiing not brought to within 18 inches of her face, BTW, but she was not blind by diagnosis), I suppose it is a matter of recognizing what a smile is when you see it and you likely have seen the videos in question and chose to not see a smile coming on Terri's face. sad really ...
just as you infer I may be seeing my desired outcome, could it be the same with you?
