Why does everything fade?

A Poem by Shadow

..

Why does everything fade?
Like a withering rose in winter...
Everything fades and sometimes
lights on fire...
Then everything dies...
Everything serves a purpose...
Or at least so we are told...
Everything has a light...
And everything has a shadow...
Everything has sadness...
Everything has sorrow...
Everything feels happiness...
And everything can't wait until tomorrow...
Everything feels something on the inside...
But please tell me...
Why does everything fade?
Like a friendship ready to be in ruins...
A friendship ready to turn into dust...
A heart that is broken and forgotten...
A heart that fades into darkness...
But please someone answer me...
Why does everything fade?
