One day, a thief noticed the calves and thought, "I shall steal these fat calves from him."
He planned and returned with a rope to steal the calves in night. On his way, he met a demon with a very hideous appearance.
The thief was frightened on seeing him and asked, "Who are you?"
The demon replied, "I am a demon. I always speak the truth and hate liars. Introduce yourself!"
The thief confessed, "I am a thief and I am on my way to steal two calves from a devoted Brahmin".
The demon and the thief struck a friendship as they were both truthful to each other, and they planned that the demon can eat the Brahmin, and the thief can steal the calves. Their works will be accomplished in the same place, so they went together.
The slipped inside the Brahmin's home and hid themselves. They waited for the Brahmin to fall asleep, when they would get the opportunity to accomplish their works.
As soon as the Brahmin fell asleep, the demon came out of hiding and readied his teeth and nails to eat him.
