Look but no Touch

The moment a tear begins,
We begin to see,
The moment a smile is spread,
We spread the chain,
The moments we show,
We cannot touch,
The moments change every day,
We each feel it,
The moments are unique,
We are human,
The moments come from inside,
We may look,
The moments cannot be touched,
We can try to hide,
The moments sneak out,
We humans disagree,
The moments origin,
We fight from heart to brain.
