Did you miss the part the student said her teacher told her that was for church?
Did you also miss the word is on the teacher's banned word list?
No, logic tells me the student is lying or at the very least embellishing a very great deal.
Did you miss the part where there is nothing that shows the poster is a banned word list or is even in that classroom? Why would a keyboarding class have such a list? Why would some of the “banned words” be categorized under “Other peer exressions”?
Use some logic.
