I saw the poster on another news site. There was nothing to show that the list was from that class (which was a keyboarding class) or that it was a list of banned words. The supposed banned “bless you” appeared under the category of “Other Peer Expressions” this strongly indicates that words were part of an in class exercise or assignment.
There have been enough people who have verified that the teacher requires silence during class time. I have no doubt the student created a disturbance then showed her butt (that’s an expression) and got called on it. She lied and I have trouble understanding how any sensible, intelligent adult cannot see this.
I know that for some people the teacher is always right but it is clear that with other students coming forward with the same story that the girl is telling the truth.
