What makes one good?
What makes one bad?
What makes one understood?
What makes one sad?
What fills one with joy?
What causes one to run?
What makes one coy?
What're the things one ban?
What makes one love?
What makes one hate?
What makes one fly above?
What makes one find a mate?
Yin and Yang collides in one's inside.
There are always rules to be abide...
