The feeling of "Happiness" Would lose and would mislay its meaning if it isn't balanced by the feeling of "Sadness"For you see
Sadness gives insight, Happiness gives climax
Sadness digs its roots for the happiness to grow its branches
Happiness is like an oak tree, growing high up to the sky
When the sadness bore its roots deep down into the core of the earth's womb
Both of these feelings are needed, and the higher the tree grows the deeper its roots dredges, simultaneously
The taller, the bigger the tree, the bigger the roots
As a matter of fact
It is always have been in symmetry
That has its balance.
