It is not that unusual to see young people who were successful in school go into teaching. This is particularly true of young women. It is an environment whose rules they have mastered. It’s easy to see why they would find it comfortable, at least initially. I suppose there could be something mildly pathological about it, being unwilling to enter unfamiliar and adult environments, but I doubt that lasts very long.
I wonder if it is even more true at the next level of education. I don’t simply mean the academic rules of engagement, but a fondness for something about college culture.
