Some Thieves broke into a house and found nothing but a Cock, whom they stole, and got off as fast as they could. Upon arriving at home they prepared to kill the Cock, who thus pleaded for his life: “Pray spare me; I am very serviceable to men. I wake them up in the night to their work.” “That is the very reason why we must the more kill you,” they replied; “for when you wake your neighbors, you entirely put an end to our business.”

Aesop was an ancient Greek storyteller, believed to have lived around 620–564 BCE, whose fables have been retold across cultures for over two millennia. "The Thieves and the Cock" is one of his shortest and sharpest moral tales, illustrating how the same quality can be a virtue or a threat depending on who is judging it.
