This document summarizes and provides context for two poems: "Languages" by Carl Sandburg, published in 1916 as part of his collection "Chicago Poems" during World War I, focusing on global social barriers and the mixing of languages; and "Mending Wall" by Robert Frost, published in 1915, about the speaker and his neighbor rebuilding a wall between their properties in New Hampshire, where the saying "Good fences make good neighbors" originated.
