Teacher's Pet?

I don't like my sociology teacher much. He mumbles, "mmm right?" after every other sentence. His presentation is long-winded, and he tries to garner student participation through questions that don't even pertain to sociology. He'd ask us to give examples about where we shop to fit a scenario he would make up, which frankly means that our participation does nothing to further our understanding of sociology.

But my biggest pet peeve is when my sociology teacher watches the clock. Wait, scratch that; there's no clock in the room. My biggest pet peeve is when my sociology teacher awkwardly stares at the students' wrists for their watches when lecturing at the front of the class. I understand if you want to keep track of the time, but staring at the clock 10 minutes into a 55 minute lecture is ridiculous. After a month of this disrespect, I felt sassy.

Today I brought my alarm clock to class. I set the alarm to 1:40pm and placed it on the desk in front of me right before the professor. I think I wanted it to be seen as a bit rude. I wanted to make a point: I will disrespect the teacher by sarcastically placing the clock in front of him since he desperately wants to be out of this classroom.

I still don't understand how unfazed he was by my act of rebellion. He even thanked me for the clock and used it twice to keep track of time. WHAT THE HECK?!
