Peaceful coexistence

I was walking toward the main entrance of my local YMCA when I looked ahead and saw a man holding open the door for me. I quickened my pace. As I approached, I smiled and was about to thank him but I stopped, taken aback. He was starring at me, unflinchingly and purposefully. While maintaining eye contact, he raised his arm and pointed at my chest in a slow, deliberate motion reminiscent of the Ghost of Christmas Future showing Ebenezer Scrooge his perdition. I followed his finger's direction down to my T-shirt. I was wearing one of my University of North Carolina shirts. I looked up and saw he was wearing a Duke University T-shirt. Then, clearly and without jest, the Blue Devil spoke. “Because I believe we can co-exist peacefully,” he said, still holding the door open for me.
