And so, when I imagine what his first night as president must have been, after he and his wife read their children books, tucked them in, and put them to bed, this is what I imagine:
Barack and Michelle embrace each other, as Michelle flirts, "Welcome home, Mr. President."
Then they race to the presidential bed, jump on top of it and bounce up and down, alternately chanting as they jump, "I'm the president," "I'm the first lady," "I'm the president," "I'm the first lady," ...
Until they collapse in each other's arms, the new President of the United States and his First Lady.
Well, that's what I would have done.
