The students are back on campus, and it’s as if the volume has been turned up again. All week it was quiet. The library computer terminals were turned off, our offices hushed; there were no lines in campus eateries. I’ve heard folks joke that a college campus is a great place to work when there aren’t students around, and I understand why: we get a chance to enjoy the loveliness, to have the terrific facilities almost to ourselves. But there’s no buzz when the students are gone; it’s really too quiet, as if the purpose has gone out of things.
