There is one in every group

Somehow in every class I teach there is one student that drives me nuts. Last semester there was the one that would always say, "We have a book?". She thought she was hysterical. I thought otherwise. This semester, the annoying one is, I think, worse. His everyday annoying activities include saying "score" any time he figures something out, most often he is just re-affirming information, everyone in the class knows. For example, we covered variance four or five weeks ago, in case you don't remember the symbol for variance is s squared. He comments almost daily that variance is s squared, when I confirm this, the inevitable score is uttered. Today, I lost my temper. Earlier this week, I had sent out an email with details on an extra credit activity for my class. The subject line was extra credit. Seems pretty obvious what the message might be about. Well today, this guy asks, "what was that email about". I replied, "extra credit, was that unclear from the email?" He replies, "I didn't read the email." At this point, I am pretty much shocked that anyone is that clueless to admit to the professor they don't read the professor's email. He goes on, "I thought it would be easier to ask you." At this point, I lost it, "I don't send this class many emails, I expect that you will read them. If you chose not to read my emails, please don't let me know, it only makes you look bad." Some of you may know that I have a very expressive face, and I have a difficult time hiding my annoyance with stupidity. Well, apparently my teaching mask, which I thought covered up those eyerolls, doesn't work. Ooops. I guess I better go to acting class.
