What do you think of me walking out on my professor?
Why did you leave when the teacher had not dismissed the class?
The teacher was an asshole for keeping us late.
Sometimes classes run late, and leaving in the middle of your professor's lecture even though technically class time was over is inconsiderate and disruptive. Stay with your class until the teacher dismisses you even if you think it unfair.
I don't think it is. I wanted to leave after class.
I get that the time limit was over but you could have missed some really important things. It is almost like a freebie you are getting extra time in school for free so he can go in-depth with the subject.
