Who is This Guy?

I think that Meursault's character is a little detached from the world and people around him. He is an observer, watches what everyone else does and compares it to his life and what he does. Even though he sits back and watches I think that in some way that he is being affected by the world, he might just be holding it in because he does want his emotions to be shown. Even though he didn't show that he was affected by his mother's death maybe in some way he wished that he knew her and that she was apart of his life. That he had some connection to her and that she played a role in who he is. It seems like smoking is what keeps him distracted maybe its his "pure being ball".
