How would you compare the attitude of the narrator and his neighbor in "Mending Wall" by Robert Frost?

The narrator does not think that putting the wall back together is worth the effort because neither of them has animals. He thinks the only reason that they would have a wall between their farms would be to keep livestock in place. His neighbor believes keeping the fence there makes them better neighbors and wants to maintain the wall.

When the narrator tries to discuss the problem of the wall with his neighbor, he gets nowhere.

And eat the cones under his pines, I tell him.

He only says, ‘Good fences make good neighbors.'

From a practical perspective, the speaker does not think they should repair the wall because it has outlived its usefulness. In the past, there might have been animals on their farms and it was needed. Now it is a waste of time and resources. 

From a metaphorical perspective, the neighbor likes to keep distance between them. He wants a wall there. The speaker doesn’t really approve. The wall is more work than it is worth. Ironically, the only time the neighbors really come into contact is when they meet to repair the wall.
