Essence of Life in The Stranger?

"Mostly, I could tell, I made him feel uncomfortable. He didn't understand me, and he was sort of holding it against me, I felt the urge to reassure him that I was like everybody else, just like everybody else."

This quote was after Meursault's fist encounter with his lawyer and it is very interesting how he sees himself and than compares himself to others. He says "I was like everybody else, just like everybody else" and it is only true to an extent. Of course he is a physical human being with an existence but mentally hes completely different. All around him he reacts differently to everything than a "normal person in his world would. He is disconnected he does't care about relationships, family, and ambition. He says it doesn't matter and maybe its true. Maybe he recognizes the essence of life and the systems all around him are just an illusion. That is why he doesn't care about relationships, specifically Marie getting married or Raymond being pals, it is just a system. How he acts disturbs people who have meaning to their live. For example, Meursault's boss is angry because he does not have ambition, Marie is upset with Meursault for not caring about marriage, the lawyer is disgusted form his response of his emotions the day of his mothers death, and the magistrate becoming angry because of Meursault athesim. All these people have a meaning to their life that their society has shaped and the odd unemotional responses the Meursault gives upsets them. I'm not sure if this makes sense but do you agree? Going back to the quote we clearly see that Meursault isn't like anyone we probably have ever encountered and his mindset of himself being the same as everybody else shows that, again he is not aware of his connections that he has with his surrounding. Not aware that people do care about things, systems.
