He only says, "Good fences make good neighbors."
Spring is the mischief in me, and I wonder:
If I could put a notion in his head:
"Why do they make good neighbors? 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 offense.
Which theme does this excerpt from the poem "Mending Wall" express?
