I've chosen to write a letter because 'it' (ja bym dala inne slowo) is very individual and emotional type of writing. The letter is written in (a gdzie przedimek?) style that 'would reflect' (to jest, wg mnie, zle, tu ma byc 'reflects') the way in which 'Chrisopher' (a nie inaczej?) speaks and thinks. I 'was focused' (to jest tak po Indian English ze az strach) on presenting how his disability 'influence' (nie, tutaj 'influences') 'on' (niepotr slowo) the way he describes events. Christopher explains things that 'does' (ale tutaj jest mowa o licz. mn. to dlaczego to slowo nie jest dopasowane do l. mn.?) not matter with excessive care 'to' (zle slowo, tutaj OF) the details. My work also aimed to present how people with autism 'precive' (hello? tutaj jest blad, slowo jest perceive) the world and their difficulties with communication. Notwithstanding, Chris 'achives' (blad ortog) his goal because now his mother 'know' (ale tutaj his mnother to jest 3os.l.poj) that her letters were hidden and her son did not know about them.
He writes about his private investigation which lead 'to to agrue' (to jest zle, bo albo him arguing with his dad, albo to the argument) with his dad. Then, there was a 'disapperance' (ortog) of a book in which Christopher was writing down (przedimek) proceedings of the investigation. Subsequently, the boy describes 'searchings' (od kiedy to slowo istnieje w jez. ang?) for the book and finding it.
At the end of the letter, Chrisopher writes that he is planning to escape from (tu cos brak) home to meet (tu cos brak) mother.
