Stressors accumulate with the semester’s approach. At a party last night, a colleague spoke with a shudder of “putting on the mask” again after having been free of it for the duration of summer break. We’re a bit like caped crusaders in that regard — particularly in our caps and gowns. Professor a persona, classroom a white-box theater. Some, of course, relish this “performance” aspect of the job. Performing is what makes the job fun, they say — and I, too, try to approach it that way. Teaching is a time-based medium; my job is to stage a fifteen-week Happening.
