Yeah but you know what? I never had a teacher that would let me reedit an essay that I had already handed in and then be graded on the new draft. Once its handed in, its handed in. Just like the OT he might like to make changes but its too late, they have already been shown in theaters, tv, and on vhs. When a movie has been shown in theaters and tv and on VHS for 20 years, I think of it as "handed it", and once its handed in, its handed in.
