Fun Introduction
Last October, Mia and Leo walked to school. Crisp air brushed their faces. Mia unzipped her jacket halfway. She said she was cool to eat a popsicle. Leo kept his coat buttoned tight. He whispered he was chilly to zip his collar. Both felt different comfort. Mia saw yellow leaves dancing. Leo noticed white puffs from breath. Dad watched them. He smiled and explained the difference. Cool means pleasantly refreshing. Chilly means slightly shivery cold. Mia understood now. She skipped to class happily.
Mia loved the sweet ice treat. Juice dripped on her hand. Leo liked the cozy coat. Dad nodded slowly. He said cool is like a gentle breeze. Chilly is like an early morning frost. Mia felt clever. She started planning her own autumn day.
