imag·i·na·tion noun \i-ˌma-jə-ˈnā-shən\
1: the act, process, or power of forming a mental picture of something not present especially of something one has not known or experienced
2: creative ability
3: a creation of the mind
Creative thought is a basic sense that we are born with, but grows dull as we suppress its misalignment within modern society. Stop saying silly things, stay within the lines, act like a grown up. We are molded to learn how to act based on 'more mature' peers within our age group, sacrificing our creative soul. I have say, when you have kids, you go one way or the other. On one hand, you can act like a 'normal' parent, with strict rules and norms that society expects, monitoring the 'fun meter'. On the other hand, one could revert to being a child, in order to gain a greater understanding. The alleged 'adult child' will begin adopting the mannerisms of their offspring, gaining a second wind of their childhood and doing such juvenile things such as making faces at the dinner table for a laugh, reading comic books and watching cartoons together, and so on.
