You ride one in to the beach, and it's the most amazing thing you've ever felt. But at some point the water goes back out; it has to. And maybe you're lucky-maybe you're both too busy to do anything drastic. Maybe you're good as friends, so you stay. And then something happens-maybe it's something as big as a baby, or as small as him unloading the dishwasher-and the wave comes back in again. And it does that, over and over. I just think sometimes people forget to wait.
