There were two hens raised in a coop: One liked to cackle, and the other preferred to keep quiet. According to the phenomenon that a hen would cackle after laying an egg. the raiser assumed that all the eggs had been laid by the cackler. Hence, he became so partial to it that all the cockroaches caught were only fed to it. However, with time passing by. the secret came to light that it turned out that the cackler laid very few eggs while the non-cackler kept laying one egg a day. Moreover, the moment the latter laid an egg. it left the coop silently, leaving the former standing next to the egg cackling loudly.

When I chatted with a friend about it. he thought what I was really talking about was not the hens, but humans.
