Ethan was feeling on top of the world. He'd just secured a spot in the school band. He walked down the hallway with a spring in his step, greeting everyone with a wide smile. A quick glance at his phone revealed a notification: Mr. Rodriguez, his music teacher, had started following him. He felt his face light up, a warm feeling expanding from his chest.

During band practice, his fingers danced across his instrument with a newfound agility. The music felt easier, more resonant. He played with a conviction he hadn't known he possessed. He was filled with a joyous eagerness. He felt like he could master any piece of music, right then and there.
