I'm curious about what you say. Most kids are a little bit rebellious. But would you have carried on a disrespectful conversation with your teacher for awhile, bluntly refusing his request (to put the phone away or surrender the phone, I don't know what it was). And then go on to refuse the request of the VP, and then refuse the requests of a police officer in uniform? I really think very few kids would do that.
I just read "Couldn't keep it to ourselves", a book written by women in prison, and compiled by Wally Lamb. Many of these women were like this. They would refuse to comply with legitimate authority when everyone else would, and one would refuse even to slightly accommodate her father, who would beat her bloody regularly. For minor things. He'd tell her to pick up that plate, or whatever, and she'd flatly refuse and she'd end up bruised and bloody.
I don't get that mentality. I really don't. Her father was a nut, and extremely abusive, but what's wrong with her that she won't do a simple thing, like her siblings all did, to avoid getting beaten? She ended up in prison, and her siblings didn't. She was missing something, somewhere that would give her enough survival instinct to get to get out of physical injury.
And that's where I see this girl. I don't think she's one of those kids whose "high spiritedness" gets them in a little trouble here and there. I think she's missing a basic instinct to avoid punishment if possible.
