Jewels of Wisdom

As part of my TA training I was told that I shouldn't make the students feel as though I have more knowledge than them.
I guess that's a good stance... Let's have the intro students assume that I don't know anything about anthropology. Surely that will foster respect-filled classroom, where they don't text their friends, play on the Internet, etc. while I go over what ethnocentrism is for the 400th time.
And shouldn't I, as a graduate student, know more about not only anthropology, but also several other subjects than the first-time freshmen I will be teaching? Isn't that the point?!?
No. No. You're right, we're all equals.
