The primary symbol in "Mending Wall" is the wall bordering the narrator's property. The physical barrier of the wall represents the psychological or symbolic barrier between the narrator and his neighbor. The season of Spring, which deteriorates the wall, could symbolize the narrator's repressed feeling that he would like the wall to come down and to have a closer relationship with his neighbor, or, conversely, it could also reinforce his desire to keep the wall in place since he is fixing it throughout the poem. The neighbor could symbolize the narrator's distrust of society, since he shows that he would like to remain separated by the fence.
