"Louisa is a teenager, the best kind of person. The proof of this is very simple: little kids believe teenagers are the best people, and teenagers believe teenagers are the best people—the only ones who don’t believe teenagers are the best people are adults. And that obviously happens because adults are the worst kind of people.
It is one of the last days before Easter. Very soon, Louisa is about to be thrown out of an art auction for vandalizing a valuable painting. The elderly ladies will scream, the police will come, and really none of this was planned. Not to brag, but Louisa had actually devised a perfect plan; it’s not the plan’s fault that she decided not to stick to it. Because sometimes Louisa is a genius, but sometimes she is not a genius, and the problem is that both the genius and the non-genius share the same brain. But the plan? It was perfect.
The auction is a place where extremely wealthy people go to buy hugely expensive works of art, so it goes without saying that teenagers are not welcome there—especially teenagers carrying backpacks full of spray paint."
