This is "the best example in all of American poetry of a wolf in sheep's clothing"

Its writer warned,"You have to be careful of that one; it's a tricky poem – very tricky". The poem is "the road not taken" by Robert Frost ~

     Two roads diverged in a yellow wood,
                And sorry I could not travel both
                And be one traveler, long I stood
                And looked down one as far as I could
                To where it bent in the undergrowth;

                Then took the other, as just as fair,
                And having perhaps the better claim,
                Because it was grassy and wanted wear;
                Though as for that the passing there
                Had worn them really about the same,

                And both that morning equally lay
                In leaves no step had trodden black.
                Oh, I kept the first for another day!
                Yet knowing how way leads on to way,
                I doubted if I should ever come back.

                I shall be telling this with a sigh
                Somewhere ages and ages hence:
                Two roads diverged in a wood, and I—
                I took the one less traveled by,
                And that has made all the difference.

至于Frost咋想的，我也揣测不了，不过两年来我从没有把第一段背出来过。我争取毕业之前完成这个任务，哈哈...
