Percy and Cho
Cho had tried to stay to herself for most of the evening. She had no desire to dine and dance, after all she was on duty. She had noted there were just as many normal citizens mingling among the masses as there were Ministry officials and people of importance. Cho had also noticed the choice of robes worm by Percy Weasley as they stood out against the majority of the crowd.
As the draw for the evening drifted away from food and more toward dancing, Cho came away from the corner where she had been standing. She walked the edge of the main crowd and finally came to rest. When she looked to her side she noticed that she had inadvertently stopped beside Percy Weasley. "Are you enjoying the evening, Undersecretary?" she asked in her most formal voice.
