The Bullfinch

Once a boy in a pet store saw a red-breasted bullfinch and asked his mother to buy him this bird. But the mother refused to buy, citing the boy's bad behavior and the coat he had ruined. He was very upset, but then, after thinking a little, he decided to correct his behavior and stopped fighting. Mom was pleasantly surprised by such drastic changes in her son's behavior and bought him a bullfinch.
