Damon looked for all the world as if he was fully occupied by the girl he was feeding on. But, at Hal's whisper, his eyes flicked in the direction he had indicated. That guys hair was more ridiculous than Stefan's. He extracted his teeth from his victim's neck, and licked his lips.
Careful not to look directly at the guy, he charmed the pretty blonde thing he was dancing with. He glanced at Hal briefly, before looking down into the girls eyes. "Forget I bit you. You've enjoyed dancing with me, but decided I was a jerk. Push me away, slap me, and then go and flirt with the guy with the stupid hair behind you."
As the girl slapped him, he pretended that it hurt, moving his head with the blow, so she didn't hurt her hand. Then he sauntered back to the bar, grinning at Hal.
