Or, that horrified look on her face when you would leave her hospital room after having said things to her that she could not repeat back to anyone?

"That evening the hospice ordered pizza and salad for us and the police, and for several hours, Brian [Schiavo], Debbie [Bushnell], George [Felos] and I camped in the room with Terri whose breathing was becoming more labored. George and Brian pulled some chairs together and kind of put their feet up, and we waited." (Terri: The Truth, pg. 314)
