Final answer:
The theme of the story is that true worth and ability cannot be judged by appearance alone, as inner qualities and actions speak much louder.
Step-by-step explanation:
The theme of the story revolves around the idea that initial judgments may often be misleading, and that inner qualities such as talent and determination are more significant than superficial traits like appearance or popularity. Sean's experience in the gym class is illustrative of the lesson that skill and ability cannot be judged solely on external factors such as height. When Sean was underestimated due to his height, he proved his worth through his excellent performance on the basketball court. This suggests the moral that one's true value is revealed through their actions and perseverance, rather than first impressions or physical characteristics. It also reflects the idea that resilience and hard work can transform others' perceptions and lead to success.
