Via Dean Dad:
Learning to manage difficult students is part of teaching. I knew a professor at Proprietary U who was fresh out of grad school, where she had been trained in finding ever-more-finely-ground evidence of social injustice in the unlikeliest places. Her first class ate her alive. Her exquisite sensitivity left her without the thick skin needed to handle actual people.
This is, in large part, what graduate schools of education do best (my wonderful wife being a glaring exception *g*).
