Write a critical notes Frost's poem and his conception of duty.

Duty is a very important value in the rural communities of New England, so it is not surprising that Frost employs it as one of the primary themes of his poetry. Frost describes conflicts between desire and duty as if the two must always be mutually exclusive; in order to support his family, a farmer must acknowledge his responsibilities rather than indulge in his personal desires. This conflict is particularly clear in "Stopping by Woods on a Snowy Evening," when the narrator expresses his wish to stay in the woods and watch the snow continue to fall. However, he is unable to deny his obligation to his family and his community; he cannot remain in the woods because of his "promises to keep," and so he continues on his way. Similarly, in "The Sound of Tree," Frost describes a character who wants to follow the advice of the trees and make the "reckless" decision to leave his community. At the end of the poem, the character does not choose to leave (yet) because his sense of duty to those around him serves as the roots that keep him firmly grounded.
