My opinion-for what it's worth- is that Talley's "Sheep and Goat" is a not so vieled put-down on someone tryin to tell you what to do.
In the end, a busy body think he or she can tell somebody else what to do thinks he or she is better than anybody else kind of person
-like the goat- gets his or her "come-uppance".

The "Sheep & Goat" story/song is in the tradition of African folktales {think Aesop's fables} which have a morale to the story or the song since songs were part of many traditional African stories.

The morale of the "Sheep & Goat" story/story is "Don't give unwanted advice" or "Mind your own bizness", or some other such truism.
