"You're up, Sam. We need you to take over at libero." The coach's words were a springboard. The familiar sting of the court lights faded as Sam's focus sharpened.

This was a surprise! He'd been a middle blocker for so long, and now, a position that would need sharp reflexes and quick decision-making. He loved the responsibility of setting up the defense. He tightened his grip on the ball and bounced it, feeling the leather warm and familiar in his hand.

He loved the thrill of the game, the energy of his teammates, the challenge of every point. His muscles felt alive with anticipation. This was a new adventure, a new way to contribute. He could hardly wait. He smiled to himself, a wide, open, uninhibited grin.
