What is the meaning of [Good fences make good neighbours]

We remain better friends if we do not see too much of one another. Our
neighbour does not live in our house and we do not live in his. Hedge or fence
between our properties are not just physical barriers; they are a reminder to
both of us that a good neighbour should never be obtrusive.
