“It’s very likely this student in question DID NOT pay attention in class, and it was a well known fact in that classroom’.”
I do believe this fact. There is nothing worse that a teacher hates than a student who does not pay attention.
If her brain is so damaged and mind is that far gone then really she should not be in the class room and should just have a private tutor at home. It’s a waste of the teacher’s time and the student’s as well. It would seem it’s too much of a stress for her and people are laughing at her because she can’t concentrate on her work.
The fact that the so-called teacher is functionally illiterate may be a basic cause of the effect. “...to not pay....is ungrammatical.” “...not to pay....is proper.”
