How much does it bug you when students can't even get it together to spell your name right on their papers?
I get this so often. It pisses me off! I may have a name that's a little unfamiliar to you, but come on!! It's there on the syllabus for you to see, and in any number of other documents I've given to you.
Today's example is a travesty that bears so little resemblance to my name, aside from the first letter, that I feel like failing the student just for that.
It's just such sloppiness, such direct evidence of a lack of effort.
