Seeing as the above article mentions that Sheehan had the chance to meet face-to-face with the President and declined the opportunity, I would tell her that she missed her chance.
I am very sorry for her loss. But she is making a mockery of the memory of her son, and only showing herself to be a fool.
As a matter of fact, if this old story had not been found late last night, she probably never would have admitted that she had a meeting with the president. Now she has to try and spin it. Or more accurately, her handlers have to give her a spin that she has to now tell the reporters.
