Personally, I think that Bush was just being mindful of the sensitities of the children. To jump up and start wringing your hands would have been very frightful. Bush comported himself magnificently.
True...but I think Bush had a whole lot on his mind besides the children. I think he was composing his thoughts for an upcoming statement while his people arranged the podium etc.
Sometimes sitting in front of a group of people is actually a good place to do some thinking.
