Mr. Henderson’s heart rate quickened as he parked the car. He’d always felt like a kid at heart. The school parking lot, with its haphazardly parked minivans and the scent of freshly-cut grass, always seemed to bring out his inner child. Mrs. Gable. Unbelievable! He remembered her teaching him how to tie his shoes.

He sauntered towards the school gates, a mischievous twinkle in his eye. He'd have to tell Sarah, his daughter, during dinner. He envisioned her reaction, the inevitable eye-roll, the embarrassed flush.

“Hey, Sarah!” he called out.

Sarah turned around, her face instantly lighting up with a smile. "Dad! What's with the bounce in your step?"

He put his hands up, grinning. "Guess who your teacher is this year?"
