Talk to the Frame!

Sure enough, and as diplomacy, and Sarcozy dictate, Kouchner had "formal" visits to pay, amongst which a visit to Saad el Hariri the son of our murdered ex prime minister Rafic el Hariri.
They were seated in the reception hall:
The entourage, then Kouchner, an empty chair, and then Saad el Hariri. On the empty chair was a frame with a picture of Saad's father, the late prime minister...
I understand that it is out of respect and all, but honestly why do we do that? It is freaky! We should stop!
Can you imagine what was going on in Kouchner's head staring at the picture of a dead guy, while cameras flashed at him?
