Frisch’s former students describe him as eccentric, nerdy, prone to lengthy classroom digressions about his stamp collection, dinosaurs or childhood snow days spent sledding. Any teacher who spends three decades in the classroom, speaking extemporaneously for hours on end to a roomful of teenagers, is going to have awkward moments. Frisch might have had more of them, and they may have been a bit more awkward. But that was how he connected, and it was perhaps a way of connecting that is no longer possible. “Everybody knew this guy was off — weird behavior, quirky,” said one parent who, fearing retribution against her child, insisted on anonymity. “Maybe in the ’70s that would have been O.K., but not when you’re paying $45,000 a year in tuition.”

Makes sense. $45k per annum ought to insulate you from quirky people.
