Gnat alighted on one of the horns of a Bull, and remained sitting there for a considerable time.
      
      When it had rested sufficiently and was about to fly away, it said to the Bull, "Do you mind if I go now?"
      
      The Bull merely raised his eyes and remarked, without interest, "It's all one to me; I didn't notice when you came, and I shan't know when you go away."
