Why Must

Why must the sky be blue,
When blue is such a sad color?
When I think of you
My soul turns blue,
But when I see your face
Or hear your voice,
I may then rejoice
And feel another color.
Yellow is nice; warm and mellow,
But may not attract a fellow.
So, get yourself back down
For your eyes of brown.
If your face turns red
From embarrassment
Or things you've said.
It's kind of nuts
To think of ruts,
That is, in words,
Stuck in our head.
