"The Ugly Duckling" tells the story of a cygnet ostracized by his fellow barnyard fowl because of his perceived homeliness. To his delight (and to the surprise of others), he matures into a graceful swan, the most beautiful bird of all. With "Thumbelina" and other tales, "The Ugly Duckling" demonstrates Andersen's identification with, and his sympathies for, the 'outsider' searching for his or her place in society.
this is in particularly true to those who get affected due a genetic cause[downs,albinos] like one patient who had this rare skin disorder[called xeroderma pigmentosa] coz of which her skin texture was completely lost and was discarded by her own father[due to nonacceptance] and hence come to our department for psychiatric evaluation.
p.s- but the truth is its her father who needed this and unfortunately no one here[in govn hosp] has the time and patience to do that.
