Harry was walking around the party holding a glass of whiskey wondering how long he would have to stay so that he wouldn't get yelled at as he looked for a familar face. He had made a donation, definitely not the biggest but he had given most of the money Pansy had paid him in the past few months. Much more than he needed considering the only thing he really spent the money on was the rent for his flat.
He had gotten a few admiring glances so far, the black robes with red tie did look good. He needed to remember to thank Pansy for them later, but hadn't really stopped to chat except to tease Ron for looking like he actually belonged in the place, and getting teased back. He had then left Ron to play host, he didn't want to do the fake smiles and compliments.
Harry grinned though when he saw 'Jack' walking around doing the same as him. "Well haven't seen you in a while." Harry teased as he walked over to him. "Enjoying the ball?" He knew this was the type of thing Severus would hate.
