The speech we hear is an indication of that which we don't hear. It is a necessary avoidance, a violent, sly, anguished or mocking smokescreen which keeps the other in its place.
A story is not like a road to follow...it's more like a house. You go inside and stay there for a while, wandering back and forth and settling where you like and discovering how the room and corridors relate to each other, how the world outside is altered by being viewed from these windows.
