Thank to TV, we now know all the jargon, and what we used to attribute to someone's personality, we now diagnose as a disorder. Thus, when Fio's friend dropped everything and moved out of state only to return four months later, Fio attributed her actions to ADD rather than impulsiveness.
But what about Fiorella, who plans every moment of her day? Fio's friend may be impulsive, but she herself is compulsive. Why else would anyone write a blog every day for more than seven years straight?
