Annoying People In Class

Today as I was sitting in class, a girl asked the teacher a question. I have no problem with people asking questions, unless they are really dumb and pointless questions. She continued to have a 10 minute long conversation with the teacher about a topic that was semi-related to what the teacher was talking about. This annoys the shit out of me. I know that I sometimes talk or ask dumb questions, but never to this extent. If you want to talk to the teacher, then wait until after class and meet with him in his office.
