Question

2. Think about Robert Frost’s poem “Mending Wall.” What does “good fences make good neighbors” mean? Why does the speaker disagree with his neighbor about the fence?

Answer 1

"Good fences make good neighbors" means, on the one hand, that the fence has divided the neighbors' properties. It keeps everything neat and clean and prevents any conflict from occurring. 

However, it also prevents neighbors from interacting and becoming friends. A fence is a barrier. It is for this reason that the speaker disagrees with the idea that "good fences make good neighbors."
