The oxymoron in the phrase "silent scream" captures the internal struggle of the narrator, highlighting the tension between outward composure and inner turmoil. This juxtaposition emphasizes the deep frustration and disappointment the narrator feels after not getting the desired role in the school play, suggesting that their emotional pain is intense yet hidden from others. The term "silent" indicates a lack of external expression, underscoring the idea that the narrator feels isolated in their distress and unable to seek comfort or understanding from their parents, who might not recognize the depth of their feelings.
The role of the oxymoron is to convey the complexity of emotions experienced during moments of letdown. By choosing to unleash this "silent scream," the narrator channels their frustration privately rather than vocally confronting their situation or seeking support. This act symbolizes a coping mechanism, revealing a profound sense of vulnerability masked by silence. The phrase effectively illustrates not only the intensity of their feelings but also the loneliness that often accompanies disappointment, reinforcing the theme of internal conflict and the struggle to communicate emotions in an understandable way.
