A warm rush of sentiment surged through David as he got out of the car. Mrs. Lee. The same Mrs. Lee who taught him to love Shakespeare. He felt a soft giddiness. Time to share some old times.

He whistled as he walked toward the school gates, thinking of his daughter, Lily. He had a story to tell.

"Lily!" David exclaimed as he spotted her by the flagpole.

Lily turned, looking at him with a smile. "Dad, you're bursting with energy today!"

He clapped his hands together, his smile radiant. "Guess who's teaching you English this year?"
