From classrooms and claustrophobia Closed

The dimly lighted corridors of the second floor were nearly empty, when Flac rushed through them. This was no wonder, as it was dinner time and the students were all gathering in the great hall to restore the energy the long school day drained from them. Flac himself was eager to join his peers at the Hufflepuff table - therefore his fast pace -, but he had to get his book back first. While he feared missing dinner time completely, he was also glad that only the portraits one walls noticed him running through the corridors this late, as he found it to be embarrassing that he simply forgot his book inside the classroom.

Well, there was the room already! As he had seen earlier, the key was sitting right in the lock. It was an old, beautiful key, but today the Hufflepuff had no eyes for the beauty of things. Instead he whispered a curse, when the key creaked when he turned it. Without any hesitation or look around, Flac  opened the heavy door and slipped into the classroom. It was dark in here, only the candlelight from the corridor was providing some form of light. Partly feeling his way through the rows of desks, Flac searched for the place he was seated during the class. The table was empty, but he could make out the shape of a book on the floor. Hastily he got on his knees and grabbed the book. Thank god, it was his. Now, nothing was standing between Flac and the pastries on the Hufflepuff table. Or was there?
