Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one travel, long I stood
And looked down 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 far that the passing there
Had worm them really about the same.
