The Road Not Taken
Explication by Matt Diamond
The traveler continues on, describing how his choice affected him and ends with him saying how sometime long in the future, he knows that he will be glad he made the choice he did.
The speaker's tone shows that he knows his journey will be long, arduous and difficult. For example, in the last stanza, he says "I shall be telling this with a sigh..." showing that the path has worn him equally as much as he has worn it.
Yet at the same time, the speaker knows he has made the right choice - for he made the choice to be different.
The poem is punctuated consistently at the end of each stanza. In this manner, each stanza is it's own sentence, and it's own thought. This shows the flow of the poem from one idea to another.
