There was once a boy who was cruel and did not care for anyone but only for himself. Once he pulled a cats tail. One day an angel saw the boy do all this bad stuff to nature and she told a doctor.
The doctor told the kid that he is not doing the right stuff and so he should stop it, but the naughty kid did not listen. He said that he the doctor had to find him another heart. She got some help from the angels.
The angels went up to heaven to find some good hearts that would be suitable for the boy. They kept bringing hearts, but the hearts were not good. Then finally they found a perfect heart for him. So from that day on he made friends with the animals and all the girls became his friend. One of the girl said “he has a heart of gold”.
