Characterization of Clara and Mae

In the excerpt below, a character named Clara is reflecting on her childhood and the relationship she had with her sister, Mae. As the narrator describes Clara's thoughts, her attitude toward Mae shifts from admiration to resentment. Pay attention to how the author conveys Clara's internal conflict.

"As I look back now, I remember the way Mae used to pride herself on her ability to charm everyone at school. I would watch from the sidelines, hoping that one day I could capture even a fraction of that light. But in those quiet moments, when we were just the two of us at home, I felt the crushing weight of comparison. Mae would effortlessly glide through life while I stumbled over my own feet. Sometimes, I resented the way she could make our parents smile and laugh, while I could barely get a nod of acknowledgment from them. It seemed unfair that she was born radiating joy, while I was left to dwell in the shadows of self-doubt."
