"Happy St. Patrick's Day, everybody!", said the teacher. "I was hoping that each one of you would wear something that is green for today. Wait a second here, I don't see somebody wearing green today. CARA! WHERE ARE YOUR GREEN CLOTHES?" "Who, me?", asked Cara. "YES, YOU, CARA!", yelled the teacher. "WHY AREN'T YOU WEARING SOMETHING GREEN TODAY? IT'S ST. PATRICK'S DAY! YOU ARE SUPPOSED TO BE WEARING SOMETHING GREEN!"

"I don't have it!", Cara replied. "But I'm wearing a yellow shirt and blue pants. Blue and yellow make green. Do those colors count for St. Patrick's Day?" "UNFORTUNATELY, NO!", yelled the teacher. "YOU MUST WEAR SOMETHING GREEN TODAY! REPORT TO THE PRINCIPAL'S OFFICE NOW!"
