Laura is known as a bit of a delinquent in the local high school. It's one of the mega-schools with thousands of students and more than a hundred teachers. It's even more of a faceless uncaring bureaucratic system than usual, to her mind. Her previous small-town school wasn't great, but it was better. There's a cop who walks the halls here, which is just a bit messed up if you ask her.
She's - more or less not capable of staying out of trouble. Late to class, falling asleep in class, 'acting threatening' in the halls because it's the only way to get the cliques to back off with the stupid insults about her hair she doesn't care enough to do something about and her clothes that she doesn't want to pay to improve. She just... Doesn't care about the school, at this point. Well, that's not strictly true. It sucks, it's not fun, she doesn't like it. But while she has to keep going, she's never going to be the ace student. She dreamt about being a pro athlete for a while, but that's absurdly difficult, hardly anyone is a pro athlete, and even after months of effort and training she's not even the best in this one school, so there's not really much point continuing to try.
She's already figured that she's going to end up in a boring, low-level job and just have to make the best of it. So, why put that much effort into school at all? They can threaten detention, poor grades, ramble about 'her future' all they like. If she doesn't actually do anything to make the school cop arrest her, like fighting or drugs, nothing that happens here will make things any better or worse for the rest of her life. She goes to class, makes a halfhearted effort, glowers at the smartass bullies, hangs out with the other 'troublemakers' at lunch, works harder than average in gym (at least being in shape is nice), struggles mightily against Algebra 1, gets on the bus to go home.
