To Be or Not To Be?

There is a fair shaking of a stick at the essentializing and stereotyping that takes place in our society which, in a cycle, influencing our thoughts and actions. Questions with less clear answers are the most interesting because understanding has to be defined by the individual. This is is the standard way of starting philosophical thinkings in my mere livelihood. I am aware that I may not be meant to understand everything but I will try to appease my curiosity to know more about those things that pull my strings. I mean we've all gotta start somewhere, right?

Ponderings of Reason

I do not understand why it is a common exception for someone to feel happy for no reason but not the transverse, for someone to feel sad for no reason. There are so many aspects of life where we get slammed with the "because I said so" reasoning that it makes sense to me. With that being my first response, it intrigues the thought of why that fuels frustration or even action in people. The real reason is unknown to the person hearing that statement thus, at least in my mind, it holds just as much value as no reason at all.

Take the instance of teaching a small child a boundary associated with an action by using this "because I said so" reasoning. What value is really placed in the child following your directions? Is it rooted in understanding or just entirely in an avoidance of a particular punishment or action regardless of the real reason why?
