One, the Other, or Between

Flight above the sky or terror beneath the earth,
There's always something between.

Light of day or darkness of night,
There's always something between.

Laughter to and fro or crying on and on,
There's always something between.

Wisdom of ages or stupidity of the youngest,
There's always something between.

Strength of a soldier or weakness of a toddler,
There's always something between.

Confidence of a public speaker or shyness of a painter,
There's always something between.

Love of two hearts or hatred of two souls,
There's always something between.

All can be reached, but foresight of which cannot be seen.
And sometimes you can even end up between.
