"Well, doesn't your textbooks say anything about it?"
"No! I've looked and looked and looked and-"
"One more look and I won't help you."
The forth year boy sighed dramatically. He had been in here since before breakfast, pouring over any material he could get his hands on. And, to the librarian's knowledge, this particular paper was due after lunch. The paper was no more written now than it was an hour ago.
"Why don't we just go talk to your professor? I'm sure they'll know something about the subject." Margaret Boyd, who had procrastinated more papers than she'd like to say, knew a few things about the staff at Hogwarts. For you see, she had gone there herself for seven years, and currently on her second year as head librarian. Head librarian came with lots of perks, including the ever important master schedule (which she was now consulting).  "Let's see... Elvish Medicine... It looks like there's a free period. Shall we go? Come on, I'll head up there with you. With the both of us, he can't refuse to help."
"Professor?" The boy would knock upon the classroom door, looking horrified next to the over enthusiastic smile of Ms. Boyd.
