you know it's ok when..

you're sitting in discussion session and say, "i was wondering why they didn't do X in the paper" and your TA says, "yeah, I was wondering that too."

yes folks, it's course evaluation time. the only time that i feel in control of my classes, armed with my potentially damaging, fully anonymous, evaluation form. time to let some professors know that students really do prefer organized lectures with handouts and that there are many more interesting things to learn about in a given semester than the crystal structure of the ribosome, i don't care if the guy who solved the structure of the large subunit is teaching the class.
