A thief sneaked into a house and found nothing valuable. Finally, he saw a cock in the yard. In order not to make a fruitless trip, he tool the cock back with him.
The cock was afraid that the thief would kill it, so he begged him, 'I, as a cock, contribute greatly to you, human beings. Every day in the early morning, when the everything is still in dark, I have already done my job, calling people to work. Please regard me as a beneficial animal to the humans and let me go.'
The thief was angry when he heard the cock emphasized its contribution of awaking people. He killed the cock right away. While killing the cock, he said, 'I must kill you just because you always hinder my work by awaking people.'
