He smiled, and added a brief "pleasure to meet you" as she left. He felt a little guilty letting her run off by herself again - really, he should've escorted her all the way to the front door. But like clockwork, he felt the biting tide of hunger beginning to wash over him - better to get rid of the girl quickly than get into a situation where he wouldn't be able to control himself.
He removed his hands from his pockets and made his way up the street, glancing around for someone else by themselves. He genuinely hoped the girl did well and found her way in the city, but being anywhere around a vampire couldn't help her very much in that regard.
He turned a corner, and went on into the hungry night.
