Today was the first day since last summer in which A) no one knocked on my office door; B) no one spotted me in the hall and commenced a conversation; C) no one saw me in the Department office. For the most part, I'm pretty social at work, at least in that superficial around-the-office-cooler way. As busy as I am right now, though, the absence of human contact was a welcome change of pace. If only I could have spent more of that alone time on something besides grading. One class down, one to go. It's going to be a long night. . .
