Sarah looked at the Professor and felt like she was a little ant, still she managed to speak after a little while. "Well it was because I was rude and very naughty, miss." She sighed. "I ask her... if her name is M..iss Brain...less and said she was losing it in her old age." She was realy sad and felt like crying. "I realy am sorry Miss and I'll make a full appology to the Librarian when I get the chance to go to the Library." She hoped the Professor could tell she was realy sorry about what had happened. She didn't know what had made her call the Librarian what she did.
