How sad do you feel?

I don't write about sadness or jokes.
I only think about the past tough.
Things which will never grow.
And the present is always getting age in my note.

Expose my bones and my brain.
Trying to see me change.
But I don't mean it in vain.
In my present the past has no end.

How sad do you feel?
You ought to hear what says the land:
-When the past forgets,The future fills.
