The light of the dark

If falls and rises blanketing me
But the thing I notice the most
And only ever truly remember
Is the extremes of the light and dark
When it's night I look for the colour
When light I explore the dark
And so I'm not scared of one
Not over fascinated by the other
I can enjoy both to the full
And I save excess for laughter
To share with my friends and soul
In the darkness and in the light
