One day a man was walking through the forest when he encountered a goblin.
The goblin shouted at the man and said: “Foolish mortal, you trespass on sacred grounds! You know not the danger that hides within these hallowed woods!”
The man happened to be Neil deGrasse Tyson, famed astrophysicist and general man of science.
Neil responded simply, “This is a public park,” and to that the goblin let out an exasperated gasp and retorted, “Well, I have a magical patch of dirt.
I swore on my life to protect it.”
Neil, bemused, responded, “This is public property, you can’t own any of it.”
“BUT IT’S MINE! THE PATCH OF DIRT IS MINE!” The goblin screeched back, his voice devolving into a hiss.
“And I will protect my patch of dirt! Since you cannot be persuaded, I will lay defenses to protect my patch of dirt!”
“You, human, should not be able to pass these defenses, but, if you do… and you THREATEN MY PATCH OF DIRT, then… I will CURSE YOU!”
The goblin disappeared suddenly as Neil dwelled upon the goblin’s choice of words, musing the word “defenses” repeatedly as he continued his walk through the forest.
Eventually, Neil came across a wall, stretching for miles and spanning the entire woods.
The wall was made of burning bricks, unnaturally luminous and searing to the touch.
Neil realized that the goblin was serious and this was the first defense he had laid.
