Mending Wall

Frost mending wall is a great poem every time I read it. It shows this two neighbors that mend their fence every year even thought there is really no need to. The speaker is trying to convince his neighbor that its not necessary but his neighbor just keeps saying that good fences make good neighbors.

              "And on a day we meet to walk the line
                   And set the wall between us once again.
                  We keep the wall between us as we go.
                 To each the boulders that have fallen to each.

I think that the wall represents something more. It seems to describe how each neighbor has gone though things that year and the boulders have fallen on them but instead of connecting with each other they rebuild the wall between them again and move on as if nothing has happened. They want the wall to stay up or at least until "their back is turned". I think he is also trying to say that there is no reason to keep this 'wall" between them they have been neighbors for a long time and they have the opportunity to share their burdens but the only thing they share is mending the wall.
