You know what grinds my gears? When professors up and change directions for an assignment after you are practically done with it already. This happened to me twice today. One was no problem (but still a 180 degree turn from before) but the other could cause me a bit of trouble. The second one I even had a hand out for which said to this this way but somebody told me that the professor told them to do it a totally different way. Great.

Man I wish this effing semester was over.
