Since she was super annoyed with those pixies all around, and mostly pulling her hair or trying to steal her wand, Nora didn't even notice that some students were leaving, once they had finished with the three toadstools. She also didn't seem to hear professor Bentley as she said that they were free to go. And now, the question was... what was she still doing there?

"Goodbye, professor," she said with a smile on her face.

No, she wasn't really annoyed because of professor Bentley. The pixies were the ones that drove her insane. She only hoped that they won't study about them in some Defence Against the Dark Arts class as she made her way out of the greenhouse.
