ADD and/or drugged - or just an asshole?

A report from an Arlington National Cemetary event:

Initial impressions were disturbing: President Bush was physically unable to stand still as the Colors were being presented -- he kept bopping his head to the march music and talking and laughing to a very still and stiff Secretary of Veterans Affairs, Anthony Principi, who was doing his best to stand at attention and ignore the president's repeated attempts to strike up a conversation during that solemn procession. All of the others on the dais were utterly still and at attention as the Colors were being presented, with either a salute or a hand on heart. Only the president was acting like a kid with ADD [abbrev., American: Attention Deficit Disorder] during a Ritalin shortage...

I had read someone's comment on another site when this happened saying how disrespectful the pResident was. I'm thinking it was not a comment from an American. But I hadn't seen any other reports on this event.
