if a person is not knowledgable or intelligent enough,
his opinion is likely not that acceptable or favored
as that coming from intelligent and knowledgable ones.
The more he knows,
the more he understands
and the more his opinions become acceptable or favored
or are more practical, useful and beneficial.
Opinions are also readily preferred
from someone with wide experience.
Experience offers great lessons and learning
making one wiser than ever before.
And the wiser he is,
the wiser his opinions become.
That's why when it comes to kids' opinions,
their weight matters little or not at all.
Kids are still very young, inexperienced
and generally carefree and playful.
They don't understand much about everything
going on around them
that's why they can't form credible opinions
that adults should listen to
for their observations are still childish.
And when they do,
they still lack the knowledge and experience to support
unless the kid is gifted
and has intelligence far beyond normal.
Almost in all cases,
kids speak what they see
and what they see is what they all get and nothing more.
But for adults,
what they see is not necessarily what they get.
They see far beyond the thing
and opinions branch out more and longer
and are more critical and more thought out.
