Boundaries exist in virtually all human relationships, and students-teacher relationships are no exception to this rule. This reality gives rise to the following question: what kind of boundaries can be deemed appropriate in an academic setting ?My opinion is that, in general, a relatively formal distance should be kept between professors and their students. 

One reason to maintain a formal distance between students and teachers is to highlight the instructor’s role as an authority figure. This is important so that the professors can enforce discipline, have instructions followed, and command respect from students.


Another reason why teachers should maintain a formal students with their students is to avoid real and perceived bias. If the teacher develops close relationships with the students, it may be difficult to completely eliminate bias. Even the impression of bias may cause some students to feel that they have been treated unfairly. 
In sum, maintaining a formal distance between teachers and students can ensure an atmosphere of authority in the classroom and avoid both real and perceived bias.
