Salinger Tone in De Daumier-Smith's Blue Period

Similar to what many of you have said, I don't believe that Salinger's tone is mocking or criticizing the depressing, blue period that Jean is going through, since Salinger himself experienced it after war. However I do think Salinger is mocking Jean's innocence or often lack of it when he tries to create this corrupted alter-ego. As we have seen in many of the past short stories, Salinger's tone often criticizes the loss of innocence in society and how corruption has taken over, and this short story is no exception.
Jean has created an alter-ego that consists of his "dead wife" and parents that are very close friends with Pablo Picasso(who also had a blue period), as well as his home in Southern France. Throughout the story, you see Jean struggle to fit in his alter ego and the reality that is his depressing life. Salinger makes fun of Jean's somewhat ignorance when Jean talks about how "(he) drew people in evening clothes stepping out of limousines on opening nights-lean, erect, super chic couples."(206) It is obvious that Jean is confused by this high class lifestyle, while Salinger loathes it. The way Saligner has Jean describe his drawing shows that he understands the corruption around him, but not where he fits in. As for Jean's alter-ego, Salinger mocks Jeans lack of ability to live up to this character that he has created. "For one thing my mustache, however sparse, was all mine"(221) shows this young man, who is obviously only familiar with the innocence in the world, trying to be this classy, sophisticated man. Salinger mocks Jean because he knows how much of a phony he is, but continues with the lies when he says "Had old Fu Manchu known from the beginning that I was wearing, among other misleading attachments and effects, a nineteen-year-old boy's mustache?"(220) In some ways, Jean calls himself out here, telling the reader that he is a nineteen year-old trying to fit into the life of a corrupted man. Salinger reiterates Jeans innocence by mentioning how Jean hears moaning coming from Yoshoto's room, but is oblivious to what it is. Along with that, Jean references the color blue(innocence) many times especially with its relation to the white(pure) goose painting.
Clearly, Salinger's tone doesn't reference(in a mocking way) Jean's depression or blue period at all, however his oblivious attitude towards the corrupted society around him does cause Salinger to criticize his corrupted alter-ego, and lack of innocence.
