Matilda

“People are shitty for a lot of reasons. Sometimes they're just shitty people. Sometimes people have been shitty to them and, even though they don't realize it, they take that shitty upbringing and go out into the world and treat others the same way. Sometimes they're shitty because they're afraid. Sometimes they choose to be shitty to others before others can be shitty to them. So it's like self-defensive shittiness.”
― Jennifer Niven, Holding Up the Universe
