You must know the childish tale of the Three Billy Goats Gruff, the actual tale was not as sweet as the one you may know.
Once a year three friends, two young human boys and a dog, join for a feast in one of the local restaurants. Except the journey to one of their restaurants was over an old bridge.
The thoughtless dog was the first to cross the bridge. His paws had hardly touched the bridge before a wolf confronted him.
"Good evening." The wolf's grin widened, revealing her sharp jaws. She pulled out a small shred of red fabric from between her teeth.
Filled with fear, the Great Dane selfishly said, "My Master is coming too. He's much bigger, and human's flesh is by far tastier."
The wolf thought, "Don't spoil your appetite. His Master will be a better meal for my hungry stomach." And she let the animal pass in peace.
Sure enough, soon afterward the human appeared. The wolf was about to pounce on him, when he -filled with fear- said, "I am very skinny, but my friend is coming too. He's ten times as large as me!"
"Stop!" thought the wolf. "His friend is larger and will be a better meal for you. Wait to eat until he comes."
Finally the final 'friend' approached. The wolf's heart laughed inside her trapped form when she saw the stately fellow. She was about to spring on him and grab him by the throat when two things caught her attention: the boy's gun and his bag.
"Tell me, boy," what is that you're holding, and what is that bag for between your legs?"
"Oh," replied the blond, "These are a pair of pistols, and the bag is where I carry my bullets."
In that moment, as such humans often do, he shot the monster in the head, she swayed over the bridge and drowned in the river below. And there the poor villain lay. She only wanted the biggest and fattest mouthful of flesh, but instead got nothing - but pain.
