There are three types of interrupters:
1. Serial commenters. Their body clock is set such that every 5 or maybe 7 minutes, their arm spontaneously shoots their hand into the air during an otherwise fluid lecture. I honestly think some of them cannot control it. However, this does not make me any less agitated when they ask their 9th question, tell their 4th story, or suggest their 20 bajillionth thoery on the purpose of all things.
2. Blurters. A cousin of the serial commenter, once removed. They have the same tendency toward spontaneity, but lack the self control required to actually raise their hand before speaking. I'm sorry you are a college junior and don't understand words like panacea... but is it necessary to blurt out "WHAT DOES THAT MEAN?!" in the middle of the professor's sentence? Twice?
3. Unrelated Questioners. If we are talking about urban crime rates, please do not raise your hand to ask what the teacher's favorite type of ice cream is. Enough said.
Obnoxious Interrupters must go.
