"Oh, come off it, princess," Harry retorted in response to all of Draco's attempts to egg him on. He was smirking despite himself, and he did wonder what Ginny would think of all this. This sudden, random friendship with a Malfoy of all people. But the war was over. He'd saved Draco's life twice during the final battle, once by accident, but because he'd known that Draco wasn't the killer he was forced into pretending to be. Besides, this Draco was even calling Ginny "Miss" Weasley, which would be startling enough to both of them.
As they started to walk towards Madame Malkin's, going inside for the first time, Harry grinned wickedly as an idea sprouted in his mind. He could really get the press rolling with only a few words. Harry stepped up to Madame Malkin and smiled sweetly. "I'd like to purchase the newest Firebolt, and whatever this git wants is on me." Harry was grinning like an idiot, his gaze trying to feel for Draco's reaction to see how the Malfoy heir would respond to that one.
