Are you open with this hobby?

I read manga in class so Im not really hiding it, I guess? Its funny, I sat with a friend at the beginning of semester, then he stopped going to class, but by the end of the semester, there were like 3-4 people sitting right behind me. What they were doing? You figure that out. Yes, my prof was that boring. 20 people showed up in a 80 person class xD
