A student just came in to talk to me (before class, so she gets kudus for that) about turning her final essay in late. I told her I'd accept it, but there would be a grade penalty.
After she left, my office-mate said that he sometimes wondered about what characteristics were common to students throughout the world, and what were specific within a culture, and we both agreed that turning things in late was probably common to all students. And to all professors. And pretty much most every one else.
I should start a quick poll on how many of my students will not be prepared to turn in their essays today.
