What is the interpretation of "Mending Wall" by Robert Frost?

This, as other Frost poems, is delightful in its
ambiguity, and there are certainly several interpretations to its meaning. I will offer
mine.

The poem is concerned with the obvious divide between
two neighbours. Their farms - both arable - are separated by a wall which is annually
attacked by both nature and man, and each year the two neighbors embark on rebuilding
this divide.

The purpose of mending the wall seems to have
different meanings for the two men. For the narrator, it is an opportunity to socialise
with his neigbor, to embark on a task together. For the neighbor, it is a necessary act
to maintain the gulf between them. The neighbour retains his 'savage' view that
-

“Good fences
make good neighbors.”

Whereas
the narrator sees the wall itself as unnecessary-

And eat the cones under his

However, for the time
that the two men are 'mending wall' they are unified despite their
differences.
