Do you live in Red Deer Alberta? lmao, because i just read that story a day or so ago. the theme is (at least one of them)
"When mankind is faced with a dire dilemma of saving a precious life or escaping to save themselves from harm, the righteous will rise above and protect the weak and the innocent from the cruelty of the world."
The Ewe represents the innocent or the weak in life,
The Dingo represents the cruelty and evil in life,
and The Man represents mankind in general,
The Island is a 'Microcosm' and represents the world.
Microcosm: A place in a piece of literature that is meant to represent the world and mankind.
