If no student arrives within the first 15 minutes of office hours, then I will assume that no student will be coming for office hours that day unless other arrnagements have been made. In this case, I will attend to my other University duties, and so I may leave my office at that time. However, it is important to remember that you are always free to make an appointment to see me at a time other than the scheduled office hours. You can arrange such an appointment by either speaking directly with me in person, by phone, or by by email.
