I can’t remember anything wildly wrong. Closest I came to that was from a private tutor my parents had to hire to make up for too many days I missed due to health problems one semester. One day when we were covering evolutionary biology she goes, “Well, I don’t believe in this, but I’m obligated to teach it to you.” Doesn’t inspire a lot of confidence, but I appreciate the candor. Also I remember a girl in my class in middle school saying her grandmother believed dinosaur bones were put there by the devil and the teacher had to give an awkward response to that.
