Defied: Annie and Billy dye their hair and style it completely different than their parents. They wear different clothes than their parents do and try to be the opposite of their parents. (For example, if Alice was The Chick, then Annie strives to be the Action Girl. If Bob was the quarterback on the football team, Billy joins Chess Club at school.)
Discussed: "Those kids are just like their parents! Freaky!"
Conversed: "I know! Don't they, like, wanna be themselves or anything?"
Implied: Alice and Bob contemplate how they'll deal with having only one of themselves in town when Annie and Billy move to another city.
Deconstructed: Annie and Billy are just like Alice and Bob, because they've been raised to be. Alice and Bob wanted mini versions of themselves, and they got miniature versions of themselves, perhaps to "live through" their children. Annie and Billy, however, are reaching the age where they want to be themselves.
Reconstructed: Annie and Billy learn to be themselves, but still retain some of the best character traits of Alice and Bob. Even if they did happen to change their hair and style of clothes, and develop their own personalities and interests. Because they have Alice and Bob's good traits, the next generation is even more successful than the last.
Played For Laughs: Annie and Billy resemble Alice and Bob so closely it hurts, but are not Alice and Bob's children, and are not even related to Alice and Bob.
Played For Drama: Annie and Billy struggle to learn to be themselves, and not copies of their parents.
