Which line in this excerpt from Robert Frost’s “Mending Wall” suggests that the speaker and his neighbor are quite different? There where it is we do not need the wall: He is all pine and I am apple orchard. My apple trees will never get across And eat the cones under his pines, I tell him. He only says, "Good fences make good neighbours." Spring is the mischief in me, and I wonder If I could put a notion in his head: "Why do they make good neighbours? Isn't it Where there are cows? But here there are no cows. Before I built a wall I'd ask to know What I was walling in or walling out, And to whom I was like to give offence. Something there is that doesn't love a wall, That wants it down."
