Be nice to me

Uh, I've gotten a few emails because of a few errors in my posting of the answer key. Please keep in mind I'm doing a special service here. I appreciate you using a much more civil and respectful tone, even when I make a mistake. If you guys lapse into talking to me like I'm a pal or a dumbass I'll cut these modes of communication and make you come to my office.

As a prof, I think you should speak to me as if you are talking to a guy who has the power to hire and fire you.

Thank you for your understanding.
