But of course Anotexia is something really sad and nobody should joke about that. But personally I wasn't laughing at both Nikki and at these girls who suffer of Anorexia cause it's something dramatically terrible but when you read this in first place or when you watch a scene like that is quite funny.
But if you laugh at Nikki knowing that she's anorexic, it's quite sad indeed.
That's the big difference.
