comfort and joy

Someone told me that we are basically cave men.  We retreat in the dark to rest. Should i say that we are like bats too? 

I can understand that.  We all seek some semblance of night during the day once in a while.  Inasmuch as sunlight is healing and cheerful, a bit of shade is soothing and draws inner reflection.

Fireflies love the darkness of night. Responding to the firefly in me gives me the joy of letting my light flicker and shimmer through which is only made visible by that stark contrast.
