Reading Passage
It was the day of the school’s Valentine’s dance. Emma wore her favorite red sweater, even though it always made her feel like a red flag walking through the hallway. When she arrived, her best friend Jay gave her a red apple smile and waved her over. The music was loud, and the lights were flashing like red magic. Everyone was ready to paint the town red.
In the middle of the fun, someone knocked over the punch bowl. Red drink spilled everywhere! The principal blew his whistle red alert! Everyone froze. Emma saw red as she realized her little brother had done it. She pulled him aside, red in the face, and tried to help clean up.
Soon, the mood lightened. The DJ played a slow song, and Emma had a red dance step moment when Jay asked her to dance. It was a red bubble moment she wouldn’t forget. Later, the principal said no one was in the red, and all was forgiven. Emma smiled what a red-letter day!
