Horizons are not the only way to view sunsets
you can watch the way they kiss every last thing good night
every thing except one accepts the temporary absence of the sunlight
the sea is the exception
the sea rages as though the sky is on fire
the waves grasp the shoreline      
the sea is inconsolable,
roaring over the suns goodbye

On a level far less grand and mad as the sea, I can relate.
even though you,
I mean the sun,
shall return in the morning,
your "good night"s will still be goodbyes, and byes are never any good.
so until morning        
I'll be restless, as the sea.
