Actually, Robert Frost did NOT say, “good fences make good neighbors”. Please re-read the poem. It is the poet’s taciturn neighbor who says this. What Robert Frost says in his voice in the poem is found in the opening line: “Something there is that does not like a wall.” (The quote may not be exact, I’m relying on memory.) The entire poem is a meditation on how walls are not good.
He never said it, he wrote it..........
