Remember, God did not use the sheep/shepherd analogy in scripture so often, just to tell you “how stupid” you are!  This analogy is far richer.  People who think sheep are only “stupid”, including others who work with them, do not have the patience or insight to see the world from a sheep’s point of view, to understand their behavior, and what motivated their choices.  Sheep are worth getting to know, and there is so much richness to learn about the sheep/shepherd analogy, why and how it illustrates the Christian’s relationship to Jesus as Shepherd, so well!
