The Gnat and the Bull
A gnat that had been buzzing about the head of a bull, at length settling himself down upon his horn, begged his pardon for incommoding him. "But if," says he, "my weight at all inconveniences you, pray say so and I will be off in a moment." "Oh, never trouble your head about that," says the bull, "for 'tis all one to me whether you go or stay and, to tell the truth, I did not know you were there."
The smaller the mind the greater the conceit.
