The Meter, The Measure

A hill is a hill
Because the valley exists
But for low plains
The highlands would deny their name
I am tall
For the reason that you are short
The blackness of me indistinct
If you weren’t so white
We must coexist
Else be nonexistent
True identities fade
Where interdependence is ignored
You are my yardstick
Much as I must be the measure
The meter by which you must shine
That shine that’s so divine
