"There are those whose own vulgar normality is so apparent and stultifying that they strive to escape it. They affect flamboyant behavior and claim originality according to the fashionable eccentricites of their time. The claim brains or talent or indifference to mores in desperate attempts to deny their own mediocrity. These are frequently artists and performers, adventurers and wide-life devotees.
Then there are those who feel their own strangeness and are terrified by it. They struggle toward normalcy. They suffer to exactly that degree that they are unable to appear normal to others, or convince themselvest that their aberration does not exist. These are true freaks, who appear, almost always, conventional and dull."

Arturo is a carnival freak, born with flippers instead of arms and legs. Good stuff.
