tree to sun [ old posting resurrected

As a small tree I waited for you to return, to bathe in your warmth and in return, I filled the air with oxygen .
But now I can't take any more, my leaves no longer grow, to shade the ground below
my roots are now exposed, as the earth is washed away by the driving rain.
The sap these branches once held has dried out, I hold no oils to keep me alive.
But still I stand tall, you are not to blame, you were always a friend to me.
Along with the rain, so my friend as you slowly fall I bid you farewell till another day,
as you are the brightest star of all .
