The Christian Science Monitor reports this human interest story from Oslo:
Before picking up his prize and delivering an eloquent speech, the president and first lady visited the Nobel Institute to sign a guest book in the room where the Nobel Committee meets to vote on prizes. Mr. Obama carefully wrote seven lines of text, prompting Mrs. Obama to ask, “Are you writing a book?”
No, Michelle, if he had been writing a book Bill Ayers would have been there.
