The same place - morning and night

When I went to university, I used to have classes at night. In a semester, I decided to enroll in a couse which classes were in the morning. So, I could notice the difference in the environment. In the morning, the campus was full of people (students, professors and employees), all the rooms were occupied and all the service departments (library, IT, administration, etc.) were working. At night, the number of people were lower, there were a lot of empty rooms and the service departments were partially working or they closed early.
