Norms, folkways, and mores

Is it difficult to identify them? Why?
Discuss the importance of these in American culture. Do any of them seem silly, irrelevant, etc.? What would happen if someone “broke a norm” (not a law)? How would people respond? Why?
If your parents/grandparents were to make this list would it look the same/different? What do these differences imply about the social changes that have taken place in our society? Has cultural leveling influenced any of these changes?
