A story is a tale told of an instance similar to life unto a certain end. It often contains the Plot, which is its core matter.
By this Law, we mean that any story told is drawn from life’s experiences common to man or which man is familiar with and this is told for a reason or purpose. This purpose may be to encourage, to warn, to say something about something, to change a way of thinking about certain subject matter, &c. Often times, some modifications are allowed under fiction situations to buttress the point properly.
The idea behind this piece is not to labor my audience with too much explanations. It is only to introduce the Story Law. That is a rule that defines what the story is and guides its making. It provides clue to how a story may be derived and hence followed through.
I hope this has helped!
