Ethan, a curious three-year-old boy with tousled blonde hair, wanders towards the sandbox, his eyes wide with wonder. Bethany, a confident six-year-old girl with dark curls and a bright smile, is already there, building an elaborate sandcastle. "Can I play too?" he asks, his voice full of excitement. "Of course! Let's make the biggest castle ever!" Bethany replies, her hands busily shaping the sand.

Ethan carefully fills a bucket with sand, handing it to Bethany, who expertly adds it to their growing structure. They exchange smiles, a silent understanding forming between them. "You're really good at this," Ethan says, admiring the intricate towers. "Thanks! We make a great team," Bethany responds, her eyes sparkling with delight.

Ethan and Bethany sit side by side on a bench, sipping juice boxes and watching the sun slowly set. The vibrant colors of the sky reflect in their eyes. "I like playing with you, Bethany," Ethan says softly. "Me too. You're my best friend," Bethany replies, a warm smile spreading across her face.

Ethan looks at Bethany, a thoughtful expression on his face. "Can we always play together?" he asks, a hint of worry in his voice. "Yes, always," Bethany assures him, her voice filled with sincerity. They clasp hands, a promise sealed in the simplicity of childhood friendship.

Ethan and Bethany reluctantly part, but not before exchanging a quick hug. "See you tomorrow," Bethany says, waving as she walks away. "Tomorrow," Ethan echoes, his heart full with the promise of more adventures to come.

Ethan lies in bed, his mind replaying the day's events. He smiles, knowing that Bethany will be there again, ready to create more memories. As he drifts off to sleep, he dreams of castles and friendship, a bond that will carry them through the seasons of childhood.
