"In the time it took for their coffees to arrive, Roger Davies and his girlfriend had started kissing over their sugar bowl. Harry wished they wouldn't; he felt that Davies was setting a standard with which Cho would soon expect him to compete. He felt his face growing hot and tried staring out of the window, but it was so steamed up he couldn't see the street outside. To postpone the moment when he would have to look at Cho, he stared up at the ceiling as though examining the paintwork and received a handful of confetti in the face from their hovering cherub."
