These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Angst? What Angst?: Upon finding out that her parents secretly dislike and resent her, Marin's reaction is... irritation. She says that her parents have "always been like this", but the viciousness of their thoughts genuinely takes her by surprise, so it's a bit off-putting that she doesn't really seem to care all that much that her parents actually don't love her. Their thoughts make it very clear that they don't want her, that they think she's a wiseass, and that they consider her a burden; hell, the only reason they cared that she was okay after falling down the stairs was because it would have cost them more money if she hadn't been. Most kids, no matter how strained their relationship with their parents happened to be, would be devastated to "hear" their parents say such things about them. Marin essentially just shrugs it off.
What an Idiot: Stranded alone in town without a phone, Marin actively chooses to ignore the teenaged girls she also sees in the area and approaches a group of young men who are eyeing her instead. Guys who even she admits "look like trouble makers".
