As a general rule, I’m not a fan of pedantic stories that are purposely written to teach some moral.  I think they’re kinda patronizing to kids.  That being said, this story is not bad for that kind of thing.  It tells of a little pig who always wants to be first, until he races to be first to respond to a call, “Who would care for a sandwich?”  It turns out to be a sand witch who needs caring for, and who holds him to his word until he learns his lesson.  It would be better simply by removing the banner across the front cover that proclaims it “A Story About Learning to Take Turns.”  Why couldn’t they let kids think it through themselves as to what the story is about?
