[PA-RIVER]

During the parade the Os got out of the limo and began walking. After a while Barack just abruptly turned away from Michelle and headed back inside the car on one side. Michelle had a look of absolute surprise and confusion on her face and (off camera) went back inside on the opposite side of the car.
It appeared to be as if Barack was signaled by the SS that it was time to get back in but nobody, in particular her husband, bothered to tell Michelle.
