This is key, because it answers the most important question: why? The girl in the first photo was fat, but still small enough to delude herself with myspace angles and clothing. She probably wondered if other people saw her as fat, or not. She would be nervous about looking at photos taken by other people, because she'd like some, and hate others (depending on he angle). In short, being a smallfat was causing her constant anxiety over her appearance. So instead of fixing the problem, she went with plan B - erase all the doubt by becoming an elephant.
