In "Mending Wall" by Robert Frost, the speaker tries to persuade his neighbor to understand that "something there is that doesn't love a wall." In other words, the speaker questions the need for the wall and wonders why they continue to rebuild it year after year. The speaker is critical of the wall and suggests that it creates unnecessary divisions between people. While the neighbor is focused on the practical purpose of the wall, to keep their respective properties separated, the speaker sees the wall as a symbol of the human tendency to isolate oneself from others.
