I am currently administering the final exam in my course in Ethics and Communication. This has been a difficult semester. Neither I nor my students seem to have been as sharp as in semesters past. I don't know why that was so for the students. For me, it was a matter of fatigue--I suddenly seem not to have the energy I used to have. Gotta find a way to get it back. Going to a part-time schedule in the fall should help.
