The Stranger: isn't it strange? (same copy, the problem was the font color)

I found quite strange the fact that Monsieur Meursault -main character in the novel- sees his mothers death as an annoying event, like if he'd just been cursed for life. It makes me think... if my mother passed away most of my life would. She (and my dad obviously) are the only two human beings that I know for sure would give their life for mine. They're my unconditional support; they gave me life!!!
I was awed when Meursault says things like, "... I could feel how much I'd enjoy going for a walk if it hadn't been for Maman", (Camus, pg. 12). This line can be analyzed many different ways, but I took it like Meursault thought his plans of taking a walk had failed because his mother had died. I mean, instead of remembering good old days with his mom, he was sort-of blaming her and saying, "because of you I can't enjoy my life now". He shows a bored attitude towards the funeral's preparation instead of making it a remarkable last "gift" for her, the most important woman in his life.
I feel the main character has an egocentric personality; maybe it'll change along chapters, I hope so. He doesn't give much importance to who he's sorrounded by; it's all about me, me, me and only me... what do you think?
