Yes, thanks, I agree! In fact I realized a few hours ago that I'd miswritten by including the "difference," but didn't change it and even wondered if someone would comment on it and, yes!, you have. So thanks. As for the poem, I'm no authority here and I wonder how you see it; to me "that has made all the difference" feels intentionally ambiguous, partly ironic or not, able to reflect the reader's view from different angles and distances. But in any case yes I'm completely with you in that the poem's only stable claim is about the apparent sameness of the paths where the traveller makes their choice, a choice without any distinguishing information. I suppose it does raise the question, what is this "difference," to be mentioned after a sigh, and how valuable can it be when arriving at it versus some other destination came down to a coin flip?
