She was just at the corner of his eyes, a whisp of auburn hair flicking to and fro as she laughed. Dragging his eyes back to the textbook in front of him, he tried to ignore her, but failed. This was a library, goddamn it, not a socialite's party, he thought loudly, over background thoughts of regret and shame that washed over him whenever near her. Someone needed to maintain order around here, and if it had to be him, so be it. Yeah. He was going to go over and give her a right talking to. Just walk right up. Who did she think she was, disrupting the peace and sanctity of the library? Before he knew it, his feet had carried themselves over to where she was standing, a little alcove that shielded her and a couple of Gryfindor students from the hawkeyes of Madame Pince.
The gaggle of girls looked up at him as he stomped over to them, and their expectant eyes bore holes in whatever it was he had to say. Shit. She was staring right at him, and he caught a glimpse of a joking, smiling and lightly mocking mouth and glinting eyes, before they turned into the sour expression she normally adopted when around him. He'd better think of something fast.
"Uhh..." he choked out, suddenly finding that his tongue was no longer an actually part of his body, but a separate entity that he could only ask politely to do as he wished.
"Too, uh, uh, loud. You are." fuckfuckfuck
"You lot," he said, giving a glower at everyone for good measure. Then he folded his arms, hoping to gain some of the righteous momentum that had got him in this mess.
