Sarah hummed a little tune as she skipped towards the school, clutching her daughter Lily's hand. The crisp autumn air invigorated her. She couldn’t stop smiling. This was it – the first day of second grade!

"Guess who Lily's teacher is!" Sarah announced, her voice a shade higher than usual. Lily's eyes widened with anticipation.

"Mrs. Peterson!" Sarah practically bounced on the balls of her feet. Lily gasped. Mrs. Peterson was *her* second grade teacher, all those years ago.

A wave of warmth flooded her. She remembered Mrs. Peterson’s gentle way, the way she made learning feel like an adventure. How lucky Lily was! She gave Lily an extra squeeze. "You're going to love her."
