From the article “The tricky poem: A guide to Robert Frost’s The Road Not Taken” it states

“Because in stanza 3, Frost makes clear that the roads are similar, and no one has yet walked upon the leaves on either one. Oh well, the poet sighs, I’ll take the other one next time. However, take one way you keep going that way and rarely if ever circle back to try the other.”

HOW does this sentence develop the idea that the poem is NOT as straightforward as it appears?
