翾昱斋——端木佩仪的小屋

Robert Frost (1874-1963)

THE ROAD NOT TAKEN

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.

From  my notes: 
It doesn’t matter which decision you make, whereas it matters that you MADE decision. Whatever choice you make changes your life and who you are. We can
 never go back and recreate it to make another decision.

From my homework:

I do love this poem. I think there is few people who have never read this famous poem before and I was one of them. I didn't pay attention to the tense of the word. but during the class, I realized the speaker didn't take any of those two roads at all. "I shall be telling this with a sigh"(l.16). I also learned about every detail in the poem is important.
After you take one of the road, there is no choice about that road any more. the thing you did is a fact now. we talk about probability in statistics. but if a thing did happen, the following things are the ones that are only considered.
"and that has made all the difference"(l.20). When we compare at least two things, we could get the differences. But if there is one thing, difference doesn't make sencse. Where does the "difference" come from? is it default to look back, suppose I pick the other road and think about what I would be today?
