Final answer:
In the poem 'Mending Wall' by Robert Frost, Sebastian and Nawin have contrasting views on the neighbors and the need for a wall. Sebastian thinks that the neighbors should maintain a boundary between their properties, while Nawin questions the purpose of the wall and its effect on their relationship.
Step-by-step explanation:
In the poem 'Mending Wall' by Robert Frost, Sebastian describes the neighbors as being different because he sees a need for a wall to separate their properties. He believes that 'Good fences make good neighbours.' On the other hand, Nawin indicates otherwise because he questions the necessity of the wall, wondering why they need it when they don't even have cows. Nawin believes that building walls creates a barrier and offense between people.
