Marengo (The Stranger pg.3-20)

Monsieur Meursault, seems to be tired of his life, impressed with his boss, and comepletely clueless about his mother's death. In the first twenty pages of this book, the main character which is also the narrator, gives the impression of being bored with his monotonous life. It really shocked me that he did not seem to care about his mother's death. Randomly Monsieur Meursault, goes to the movies with a girl which he used to be involved with, but after a night in the movies and in his house she just left, and he again shows no feeling about this. Can a human being be so empty inside to not feel anything ever?
