* Rachel realizes the red sweater isn't hers. The moment she pulls the sweater over her head, she knows it isn't hers. This realization is a pivotal moment in the story, as it signifies the beginning of her emotional unraveling.
* The teacher dismisses Rachel's claim. Instead of believing Rachel, the teacher dismisses her and even gets angry, further solidifying Rachel's feeling of powerlessness.
* Rachel's classmates turn against her. The other children in the class begin to taunt Rachel, further isolating her and making her feel even more vulnerable.
* Rachel's anger turns inward. This is where the falling action starts to shift. Instead of lashing out at the teacher or her classmates, Rachel internalizes her anger and frustration. This is shown through her silent weeping and her withdrawal from the situation.
* Rachel finds solace in her own thoughts. The story ends with Rachel retreating into her own world, "eleven years old and feeling forty," where she can finally escape the injustice and humiliation she experienced.
In essence, the falling action is the period of time after the climax (Rachel being forced to wear the sweater) where the tension and emotional turmoil begin to subside. It's not a happy ending, but rather a somber and introspective one, where Rachel finds strength in her own resilience and emotional maturity despite the unfairness of the situation.
