Watching the Sun Set from the End of the Road

I watched you at the end of the driveway
Staring at the sunset again
And we sat at the end of our road
As the lights all glow

When we watched as the ships fly by
And the moon is in our eyes
As they looked down at what they know
Something we don't know

And I wonder what they feel
As they watch us stare at them
And now we know what they don't know
And when we meet each other, then what would we know?
