“Mending Wall”

I agree with the line that says “Good fences make good neighbors” (Line 27). Sometimes you can be friends with someone as long as they don’t see everything that is going on. What I mean is if you have a neighbor that is always letting their animals go to the bathroom in your yard and/or they leave their toys and garbage out and it blows into your yard, you could get very upset and then the two of your could start feuding. If you have a fence up than these things will be prevented and you can get past the little things and become neighbors that respect each other.
What I don’t understand is if the wall is on their property why do they not see or hear the ball being taken down in spots? They could definitely hear the dogs barking if they are hunting rabbit. If they hunters make the holes why don’t they put the rocks back? It would just be out of respect for the owner of the property, if you break something you fix it.
