A thief went into a house, and they couldn't find anything valuable. There was a rooster, so they stole the rooster and quickly ran away . When I got home, I was planning to kill the rooster, but the rooster pleaded bitterly: "Please forgive me! I'm very useful. I can cry in the morning and wake people to work." But The thieves replied: "Because when you wake people up,  just destroyed our stealing action. This is the reason we must kill you!"
