Yes I could very easily have been this girl in my youth. Truth be told I'm still a bit on the stubborn side. I'm not sure if I could have taken it to the level of being tossed about by LE as in my case it never went that far.
I think it really just boils down (as I said) to being very stubborn.
I can tell you I have never been imprisoned or spent any time in jail,but I thought very little about speaking my mind to an authority figure IF I felt they were in the wrong. IMO
I too could have been a student speaking up like this one, definitely to a teacher one time, maybe twice in a row, but before time admn'r was summoned to classroom, I would have figured out I needed to take another tack.
Even among posters saying this teen was ___ {choose your own negative adjectives}, my SWAG is they might say the same about themselves as HS students, that they were mouthy, disrespectful, disruptive on occasion, but not to the extent of ignoring teacher, admin'r, and yet a third school authority.
(When I was in school, dinosaurs still roamed the earth, and nobody had dreamed up RSOs. LOL)
