Simon decided that he would see if the Professor was in his office, he wanted to know who created the subject of Ancient Runes because he had no idea about anything to do with the subject and if he found out who created it maybe he could find a book on the subject.

Simon knocked on the door and then started to get nervous what if the Professor thought he was being silly and told him off, he did think of the idea of running away but then he remembered he had knocked on the door, he would just have to wait and see if the Professor was in his office, he just stood there waiting.
