PARKINSON'S LAWS AT WORK? St. Cloud State University's administration has seen fit to recommend that all voice mail messages spell out that University offices are closed Fridays (is that to conserve on air-conditioning, Thursday nights to Monday mornings as is the case at Northern Illinois?) There is something to be said for opting out of summer school. My voice mail message stipulates that classes resume August 25, and regular office hours and regular call returns will commence then. If there's anything in the system for me, well, August 25 will come. There is, however, at least one assistant-to at St. Cloud who has just made a case for being made a beer vendor at Vikings games, or perhaps designing catenary poles for the Hiawatha Corridor, or removing all the Eurasian milfoil from Lake Minnetonka.
