Jason stood resolute, his eyes fixed on his sister. He was determined to prove he wasn't just a little kid anymore. "I can do it this time, Mia," he declared, confidence shining in his eyes.

Mia watched with a bemused smile, arms crossed. Jason strained, muscles quivering with effort, as he tried to lift his older sister. "Almost there," he grunted, holding on for dear life.

"Nice try, little brother. But you'll probably always be lighter than me," she chuckled, ruffling his hair affectionately.

Jason clung on, a mix of embarrassment and delight coursing through him. "Hey, put me down!" he protested, though his laughter betrayed his enjoyment.

Mia carried her brother with ease, both of them relishing the moment. "You'll get there one day, Jay," she said softly, her tone reassuring.

Jason leaned against Mia, feeling a newfound sense of camaraderie. "Thanks, Mia. You're the best," he admitted, his earlier frustration forgotten.
