Two highways diverged on a sunny spring day,
As I drove home from the coast,
And not sorry I could not travel both—
As I wanted to continue my journey homeward—
I did have time to observe that
One was fully divisible by the other, evenly by two,
with a remainder of zero.
And though it made all the difference for the mathematically-minded,
I continued on with a sigh and a smile, for I had
miles to drive before I could sleep,
miles to drive before I could sleep.
