Gym class is mind-numbing. Bella spends it thinking about introversion - Andi finds it peculiar and kept asking her questions about it. Bella's not an extreme case of the type, but definitely qualifies. Andi always has more friends - needs more friends - than Bella does.
"It's... occupying, I prefer to do it than not. I don't think fun is exactly the right word. It's very important to me, but more in a breathing way than in the way hobbies are."
"Huh," says Trouble. "I think I get it." He tilts his head thoughtfully. "I don't know if I have anything like that, though."
"Not having a thing you're attached to like I am to my introspection thing? Yeah. Andi's my benchmark for normalcy and she doesn't have one, for instance."
"Makes sense," says Trouble. "I don't know if I know any normal people. Unless you guys count. Do you count?"
"She's often better than I am about predicting how our parents will react to things, since our parents are also pretty normal."
Trouble doesn't show up to school at all the next day, but he does show up at Bella's house with cake.
