Another thing that gets me is the refusal to follow directions when writing a paper. I can't tell you how many papers I have read that are on a subject that does not come close to the assigned topic. I recently gave one student a 50 for putting words on a paper; but the fact that she did not write about the topic I assigned, did not use any kind of formatting (up to and including no name on the paper), and did not have a bibliography acted against her. Honestly--it's a little insulting.
Perhaps it's time for another walk in the woods.
Was I a more forgiving teacher when I ate chocolate everyday? (Probably not).
