I started to wonder what I was doing there

I found this line in Michel Houllebecq’s Submission:

I started to wonder what I was doing there. This very basic question can occur to anyone, anywhere, at any moment in his life, but there’s no denying that the solitary traveler is especially vulnerable.

It reminded me of:

At any street corner the feeling of absurdity can strike any man in the face.
-Albert Camus

I finished Submission last night and it’s one of the best contemporary novels I’ve read. It’s not at all what I expected it to be and apart from being superbly written, it’s left me with a lot of questions.
