Sailboats return at sunset to Marina del Rey, California (just south of the city of Santa Monica).
We all have to come home at the conclusion of the day, don't we? No matter where we've been, what we've done, how much fun we've had (or how much pain we've endured), the day, sadly or mercifully, will end. The sailors bringing these boats back to the harbor presumably enjoyed their day, if only because they knew it would have to come to an end. It is that poignant knowledge, that our days, that our lives, are finite, that makes them so poignantly pleasurable.
There was only a little time to enjoy the view. And then I had to return home.
