Brody sat perched on the edge of his treehouse, a book spread open on his lap. The laughter of children playing drifted in from the street, but he was lost in the world of words. Down below, Blakely, his younger sister, was chasing butterflies, her giggles rising like music. "Blake, come up here," he called, his voice a mix of authority and exasperation. "Okay, Brody!" she replied, her small feet tapping eagerly on the wooden ladder.

Blakely climbed up, eyes wide with excitement. Brody sighed, trying to focus on his book as she peered over his shoulder. "What are you reading?" she asked, curiosity sparkling in her eyes. "Just a story," he replied, a hint of irritation in his voice. Blakely pouted, "I wish I could read like you." This simple sentence hung in the air, echoing in Brody's mind.

Brody glanced at his sister, seeing her not as a nuisance but as someone looking up to him. A sense of responsibility washed over him. "How about I teach you?" he offered, surprising himself. Blakely's face lit up, "Really? You will?" she asked. Brody nodded, "Yeah, we'll start with your favorite story."

Day by day, Brody and Blakely sat together, fingers tracing over words, voices stumbling then growing confident. Brody learned patience, finding joy in Blakely's small victories. "Look, Brody, I can read this part!" she'd exclaim, pride shining in her eyes. Brody would smile, "That's great, Blake. You're getting better every day."

As the summer days drifted by, Brody realized the impact he had on Blakely, not just in reading but in everything he did. He saw her confidence growing, her enthusiasm infectious. "I never knew helping could feel this good," he thought to himself, watching his sister read on her own.

Blakely snuggled against her brother, a book clutched in her small hands. "Thank you, Brody," she whispered, and in that moment, Brody understood the true meaning of family. "Anytime, Blake," he replied softly, knowing that summer had changed them both forever.
