Orwell posits that there is a very short period in everyone's life when one's character is fixed forever. Given the semi-autobiographical nature of this work, it would come as no surprise to anyone that Orwell himself drifted to the emotional Left in the face of such staggering racism and snobbery. However, given his schooling, the period could have started sooner.
A desperately sad story of an 'outsider' who didn't 'fit in' and was 'unsound'. Read this and you will wonder how the map was pink.
Note that the book contains highly offensive language.
