Loneliness
While Frost's poems are often read as uplifting (think "The Road Not Taken"), there's almost always a lonely, dark side to them. Though we see two characters interacting in this poem, they are, at heart, totally lonely. Even the house where the poem takes place is lonely, with only a graveyard to keep it company. And then we get that doozy of a line: "One is alone, and he dies more alone" (105). You might want to keep this line in mind as you read some other Frost masterpieces, like "Stopping by Woods on a Snowy Evening" or "Mending Wall." They might not be as upbeat as you once thought.
