For instance, I find it interesting that he saw a picture of Hillary but saw Chelsea's face.
The implication being that Chelsea was being seen as in person, in his presence. This is an image that gives a warm comforting feeling of closeness.
Contrastingly, Hillary is there only as a picture, a representation of her rather than her actual presence. This gives an image of remoteness, distance, perhaps even cold and distant. Certainly not supportive.
Any psychology students out there?
Too bad it was near.
He tried to convince Hillary that the nurse was just giving him a sponge bath........a really good sponge bath.
