My words has no price

My words and lines
Are similar to you,
With a touch of pain
And much of freedom;
It will keep flowing
Like air i breathe,
It will keep glowing
With examples i see;
You can laugh on jokes
Praise my works,
Admire my lines
Or may auction it;
But you'll always
Have less of it,
Like drops of water
From mass of sea;
You may walk away
With a pride,
You may move out 
With a smile;
You will buy my works
But not my words,
You will buy my notions
But not my emotions.
