A teacher

The elevator door opened, and much to her utter shock and dismay Jessica found a teacher staring back at her. He was a middle-aged man, tall and gaunt, wearing a smart cardigan over his shirt and slacks.

"Well hello, there," the teacher stared for a brief second before averting his gaze, "what have we here?"

Jessica froze, and couldn't find any words to express herself.

"I take it you're new here?" Jessica could only nod at the teacher's question.

"Well, this will not do," the teacher continued, "here, come with me."
