It is perhaps best known for its line spoken by the neighbor: "Good fences make good neighbors." The poem's narrator displays a disdain for the expression and the walls erected between people, and yet he also shows a grudging acceptance (albeit sadly) of the line's truth in its application to human relationships. The line is listed by the Oxford Dictionary of Quotations as a mid 17th century proverb, which was given a boost in the American consciousness due to its prominence in the poem.
