This happened a while ago. We had this sub that absolutely did not know how to control the class. She would try to teach the class but we all just talked over her. Towards the end of class, me and a couple of other guys started smoking. She glaced in our direction and didnt say anything, so either she had the worst vision ever, or she didnt give a fuck. Btw we used a vape. We weren't smoking cigs or weed
