Although first lady Laura Bush 'very much appreciated' the wedding anniversary card she recently received from President Bush, she said she 'harbored suspicions' that its inscription is the work of one of the commander in chief's speechwriters. 'Make no mistake, my beloved spouse: This marriage has been an enduring achievement that will continue to make significant strides well into the 21st century,' the pastel-colored document read. 'As a president and a husband, I pledge to you that I will not cut and run from the greatest wife in the world. I believe marriage is between one man and one woman, and, make no mistake, I would marry you all over again.' Mrs. Bush has placed the card on the Roosevelt Library fireplace mantle next to the card her husband sent on her last birthday, which urged renewed cooperation, defined life as beginning at 50, and had puppies on it.
