Once there was an old lady who had a parrot. The parrot used to tell her the time. Every morning, the parrot would wake up the old lady and then the old lady would wake up her servant.
The servant was very angry at the parrot. Because of him, he had to wake up early in the morning. Getting an opportunity, he killed the parrot.
Now the old lady had no sense of time. She would often wake up the servant at midnight. The servant repented his sin.
