There is no end in the shades of light or is there?

Will the shades of tonight
fall upon today tomorrow?

Do shadows run or walk?
Or just creep along the sidewalk!

Why do dreams begin at nightfall?
Only to disappear at day break!

Will the light pass through the shade
at the end of the tunnel?
Or will they meet and go around!

Who came first?
Shades of light
or shades of dark?

If the stage is set
for the final curtain
will dark intervene
or will the lights come on
in anticipation?

Need the mood be dark or light,
or just a bit shady?
What side of the shadow do you stand?
Will the prism of light enter you
in return for a rainbow?
