You must be sure to include the idea of conflict when discussing rising action, climax, and falling action. The rising action is when the main conflict is introduced and the protagonist typically makes some attempts at solving said conflict. For instance, if the major conflict of this story is read as an inner conflict for Connie as she comes of age, the rising action must include how she initially begins to deal with this conflict, such as exploring her independence when out with her friends, or staying behind while her sister and parents go to a family party.
The climax is then when the protagonist typically makes a decision about how to definitely deal with the conflict. The falling action is the process of the character carrying out said decision.
