The Gnat and the Bull
Once on a time a poor gnat sat on the horn of a bull, and said, “I have made free to rest on the tip of your horn; but if my weight is at all too much for you, pray say so, and I will move off.” “I think you are more nice than wise,” said the bull. “To tell you the truth, I did not know when you sat down, so I shall not miss you when you think fit to rise up.” At this the bull gave his head a toss, and put the gnat to death with his tongue.
It is a dull bird that points out her own nest.
