This one kept me thinking the whole time. About baggage we leave behind when we move on with our lives, about people we think we'll always be with, about how sometimes the best thing something in our lives can do is...end. It feels like a story about holding on but also about letting go. It felt like, in the end, they both accepted how things had to go. You can ride that train until you're an empty husk but it'll never reach the station.
