David felt a lightness in his step as he walked down the street. He whistled the tune of a song from his childhood. He couldn't help but crack a smile every few seconds.

The prospect of his daughter, Emily, having Mr. Harrison as her teacher was incredibly uplifting. He remembered Mr. Harrison's ability to unlock the potential in his students, and he knew he could trust him with his own child.

He glanced up at the clouds drifting overhead. He felt like the world was full of possibilities. He couldn't wait to see what this year held for Emily. He felt a warmth spread through his chest.
