Once, on a beautiful summer day, he took a tourist boat around Boston Harbor, just to be on the water. He felt odd, in his suit and tie, surrounded by teenagers in shorts and T-shirts, ignoring their parents, hardly looking at the ocean, sneaking smokes back by the engine. He wanted to shake them, to shake the boy he once was, lying on a floating dock off the coast of Maine. Enjoy this, he wanted to say. Try to stay in the moment. He wished he could be one of them, to still be in that place where everything seemed possible.
