Aurélien is a very close friend who suffers from Asperger's syndrome. Among the symptoms, an atypical use of language that complicates his integration into society. His speech indeed shows a certain difficulty in incorporating the codes that govern social ties and interactions, which therefore excludes him from any lasting otherness. Beyond what autism can explain, beyond also the hypotheses that I could formulate, there is a testimony about him that interests me greatly: his own. How does he see himself, think about himself, impress himself, experience himself?
