Friendship with Professor okay? My professor and I walk to and from for every class I have with her, I am a female senior student and my professor is in her 30's. I've gotten to know her really well, we even had a random dinner together. I go to her office hours everyday and share a coffee or cookie. I go to her for many incidents, including a man who has been harassing her and me. She has a partner who she mentions all the time and she even tells me about her family situations back home. We've had several meetings with the University officials and discuss them afterwards. We email constantly, I consider her a friend or a mentor.

I'm curious to know where the boundaries are between my Professor and me (student)? What is the difference between a Mentor and Friend for professors and does it apply to me?
In my opinion professors are normal people and can have friends as everyone else, as long as it does not affect your grades and how you are treated in the classroom. I used to give classes where I taught my friend who I started studies at the same university with (he took a few gap years...). In the classroom and when grading exams and homeworks I treated him exactly as other students.

There is also a possibility that your institution's code of conduct has regulations pertaining to this situation. Nevertheless, they should be more of concern for your professor than you.
