Select a departure point and destination on a map, then put two people on a bus – chart their geographic progress as they navigate their relationship. How does being in a restricted space limit what they can say? How does the changing scenery propel them into the past? How are they changed by this journey? Who are they when the bus stops at their destination? What have they lost – or gained?

In story, sometimes it’s easier to convey change when the characters are literally traveling from one point to another.
