Enigma

What is this feeling, is it sun or is it rain?
Is it blood or water?

She doesn't smile back,
As she did, that one day.
That one smile,
With those eyes

Instead today she looks on
And the world seems, pale.

I stand, wondering
What could it be
That keeps her from smiling
Praying it's not I continue along

The feeling can't be rain, can't be sun
No.
The feeling is the still
Before the storm; simply the prelude.

To what?
