an interesting observation

cf.

Robert Frost, Stopping by Woods on a Snowy Evening:

The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

AND

Leonard Cohen, A Thousand Kisses Deep:

And maybe I had miles to drive,
And promises to keep:
You ditch it all to stay alive,
A thousand kisses deep.
