On my way, I was learning, was the product of Barack’s eternal optimism, an indication of his eagerness to be home that did nothing to signify when he would actually arrive. Almost home was not a geo-locator but rather a state of mind. Sometimes he was on his way but needed to stop in to have one last forty-five-minute conversation with a colleague before he got into the car. Other times, he was almost home but forgot to mention that he was first going to fit in a quick workout at the gym.
