The entire storybook of the The Ugly Duckling, the book should be about self acceptance and learning to be happy with not being a normally attractive being in society, but by the end of the book the duckling doesn't have an epiphany after all the shit that he's been through being shat on by other animals and even his own family, to be like 'Im different, I can be happy with that, fuck them! Instead, the dude turns into a beautiful swan for no reason at the end and is accepted for finally being of a high enough standard to cater to societies shallow outlook. Its basically unintentional or not saying 'If your not beautiful your life is worthless unless you change yourself to cater to other peoples opinions even if they treat you badly' Real nice message to give to like the 4 year olds who first read that guys.
