Robert frost uses the image of a cross road in order to symbolise what is it like for human beings to make difficult decisions.
For example, Frost describes ‘two roads diverged in a yellow wood’ to show a moment of indecision.
The two roads present the walker with a choice. The road that he chooses to take here will impact the rest of his journey. The fact that he is unable to see the outcome of the journey means that he must make a blind choice as in the poem he chooses the more ‘different one’.
This is extended metaphor symbolises the ‘roads’ we choose to take within our lives. It can often feel as though human beings are confronted with an importat choice that will determine the rest of their lives, also when the writer describes the forest as a ‘yellow wood’ he is telling us that it was autmn at the time, it could also signify a time of happiness. The metaphor symbolise. Moments of indecision.
