The Gnat & the Bull

 Author: Aesop

With unusually loud buzzing for such a small creature, a gnat flew over the meadow and landed on the Bull's horn tip. After a brief period of rest, the gnat got ready to take off by flying. But before he left, he begged the Bull's forgiveness for using his horn as a place to rest.

You must be very happy to have me leave at this time, the gnat said to the bull.

The Bull answered that he had no idea that a gnat was sitting on her horn, even the bull did not feel anything sitting on her horns. 

Moral:

We often place ourselves above our neighbors in terms of importance. The greater the conceit, the smaller the mind.
