Who is this Guy?

Meursault I believe is secretly a sad man , making his thoughts very dark and his relationships suffer. I believe he is human because he has feelings and thoughts, even if it is that everything is meaningless. It personally makes me feel depressed because the way he talks about of his life, makes him seem detached. Things are going on and he seems to be just the observer not really contributing anything. For example when he was at his mother's funeral, he observes the room, the smell instead of really mourning his mother's death during the funeral, " It was pleasant; the coffee had warmed me up, and the smell of flowers on the night air was coming through the door. I think i dozed off a little."This book kind of reminds me of perks of a wallflower because they both go through their life watching others live it. I don't know anyone like Meursault but maybe we all have a bit of him, sometimes we try to hide our feelings causing us to ruin our relationships or we can have a dark or detached feelings with an event of our life. I believe that one thinks people should be "normal" not weird or too dark because it's what society would like us to be. Maybe Camus made this character this way to makes us think of why this character is like this or maybe to make us see a different way a person can live his/her life. Everytime you meet someone it's like starting all over to make connections, to see if will be friends or maybe just 2 people who just know each other. But it seems like the character always feels like a stranger but doesn't do much to change that. I want to keep reading to find out why Meursault is the way he is??
