In “Mending Wall”, Robert Frost has beautifully presented two seemingly different ideas. First he says that there is something that does not like walls. It makes the frozen ground under the wall expand. Because of this expansion, the wall gets cracks, making the upper stones of the wall fall down to the sides, thus making gaps. Sometimes the gaps are big enough to let even two people pass, walking side by side. This means there should be no walls between people. But people divide themselves by buildings walls. These walls come in the form of gender, religion, isms, races, position and wealth. These walls are artificially made by people and they should be demolished.
Frost further says that “Good fences make good neighbours”. We may not like walls but they are necessary for keeping peace between neighbours. Imagine our neighbour’s goats coming and eating the beautiful plants in our garden. We will defnitely not like it. Similarly if our dog catches the chicken of the neighbour will he like it? So walls are needed. But such walls are not always necessary as in the case of Frost and his neighbour. Frost cultivates apple. His neighbour cultivates pine. There is no possibility of his apple trees getting across and eating his neighbour’s pine cones. Nor do the neighbour’s pines get across to eat the apples of Frost. In such cases, Frost feels, walls are quite unnecessary.
