Baxter was not as attached to his yearbook as others were. He saw no reason to get so excited about a book full of pictures. Perhaps when graduating- but in the mean time, it was just... odd. They weren't going to never see their classmates again or anything, even when graduating the wizarding world was small and you would surely run into people on a regular basis. Even so, Baxter knew that it was standard to ask others to sign his yearbook. So when he saw groups of students, he would always drop his yearbook into the fray to get signed- not caring who signed it or really what they wrote. If he disliked what they wrote he could charm it out later.
