What are their feelings about the wall and the joy of building it?

Every year, two neighbors meet to repair the stone wall that divides their property. The narrator is skeptical of this tradition, unable to understand the need for a wall when there is no livestock to be contained on the property, only apples and pine trees. He does not believe that a wall should exist simply for the sake of existing. Moreover, he cannot help but notice that the natural world seems to dislike the wall as much as he does: mysterious gaps appear, boulders fall for no reason. The neighbor, on the other hand, asserts that the wall is crucial to maintaining their relationship, asserting, “Good fences make good neighbors.” Over the course of the mending, the narrator attempts to convince his neighbor otherwise and accuses him of being old-fashioned for maintaining the tradition so strictly. No matter what the narrator says, though, the neighbor stands his ground, repeating only: “Good fences make good neighbors.”
