One of the "taboo topics" is that there are individuals in this business who are neurotics.  They may or may not be instructors.  They could be anyone in the organization.

These individuals have more than the usual and "normal" psychological baggage that we all have to one extent or another.  Theyare, as we say, "certifiable."

When these dragons are lose they make everyone around them miserable. 

I had the opportunity of tracking one of these individuals as an unofficial consultant to a school manager and an instructor.  It is a wonder that the school did not get sued. 

These individuals can make the students miserable, destroy the reputation of the school, and wreck the organizational culture.
