Classes begin for the Fall semester tomorrow at Case Western Reserve University, my fine employer. The kids have been coming back to campus for the past week, with the last new student orientation session last Monday and Tuesday. I have the same feeling that I always do: It’s good to see the students back (they do pay my salary, after all), but it depresses me that the summer is over (when did it begin?) and all too soon cold, dark Cleveland weather will be back.
