Actually, DT probably knows that teachers will keep some of their students 'works' as examples. I had a professor tell me that she was keeping some of my 'reflections' on male dominance and specifically a rape theme.
oh, Dt already mentioned that ... she probably was trying to motivate you. I never understood English teachers. They for the most part are so pedentry ... no, just kidding, pedantic.
One of the main reasons I hated and resented school to the max, starting in elementary school.
