In mid adolescence, during the late middle school and early high school years, most rebellion is about creating needed differentiation to experiment with identity and needed opposition to gather power of self-determination.
This reminds me of the play, Romeo and Juliet, because both characters are in mid adolescence, and rebel in order to be together. They are in search for power over their own lives. For example, Juliet rebels by not marrying Paris and pretending that she is dead.
