In “Mending Wall,” Robert Frost uses analogies to demonstrate the barriers in a damaged friendship. Frost's analogies are used in the themes of barriers, nature and walls. Throughout the poem, Frost uses metaphors to allow the reader to see the wall, which separates the neighbors from a different perspective. His use of comparisons appeals to the reader because, as a reader, they are things we can relate to and experience in life. His use of analogies allows the reader to imagine a friendship being destroyed. In the poem “Mending Wall,” the friendship between the speaker and his neighbor is damaged. They have both physical and emotional barriers. In lines 40-42 he says, “before I built a wall I would demand to know what I was walling in or out of and who I might offend.” It is clear that the speaker does not like this idea, and this is both a physical and emotional barrier. In lines 10-14 the speaker says, “The gaps I mean, no one has seen them or heard them made, but in the spring we find them there.” The speaker and his neighbor went a long time without noticing the gap that was forming between them. This is an example of a physical and emotional barrier. In lines 48-49 the speaker says, “Carrying a stone grasped firmly by the top in each hand, like an old savage armed with a stone. This is also a physical and emotional barrier. These barriers are also demonstrated in the use of nature and metaphors. In the poem “Mending Wall” the speaker often talks about a wall. In lines 40-42 he says, “before I built a wall I would demand to know what I was walling in or out of and who I might offend.” A wall can symbolize many things. It can symbolize an emotional or physical barrier. The wall is physically served... in the center of the card... that wants the wall to be lowered. The elves are used as a metaphor for the forces that are causing the wall to collapse and forcing them to rebuild it. Even the definition of elf speaks of malicious interference in human affairs. Therefore it makes sense why the neighbor would say that the elves are the cause of the wall falling. Frost's use of analogies causes the reader to feel as if they are one of the neighbors in the poem. His use of comparisons engages the reader, because they are very pragmatic. His work is full of barriers that we as people experience in relationships and can relate to. After reading this poem the reader has a better understanding of what the wall really symbolizes. “Mending Wall” allows the reader to see the poem from a different perspective and put themselves in the speaker's shoes..
