Who is this guy?

I think this guy is what the title implies: a stranger to us. He makes me feel depressed and confused by not showing any of his emotions. In the beginning of the book, he portrays a sense of detachment from his mother, the person who brought him to the world. We wonder why he is so indifferent to his mother because we are expected to show sadness and pain in similar situations. By the end of chapter two, the character lets the readers know that he is able to continue his life without complications. It is as if his mother has no affect on him and that he shows no care for his mother or anything in the world. Realistically, people would shed tears and stay in bed for days but the character goes out to make love the next day. I think Camus wants us to be confused and feel different from the character. I find it hard to connect with the character. In a way, we are a stranger. We are unable to understand him and he is unable to understand us. The character and we are strangers to each other.
