Maybe this is how it goes, I think, watching Beth and Melanie, remembering the people I have loved, and the ones I wish I hadn't lost. Maybe we are all Beths, boarding other people's life journeys, or letting them hop aboard ours. For a while we ride together. A few minutes, a few miles. Companions on the road, sharing our air and our view, our feet swaying to the same beat. Then you get off at your stop, or I get off at mine. Unless we decide to stay on longer together.
