Don't look at my book!

I'm currently reading Nabokov's Lolita. Today I am taking the train into the city for an appointment, but I'm apprehensive about bringing that book. It's creepy, right? A middle aged man alone reading Lolita on a train. I can't do it. This is a normal line of thought, right? I'm taking a different book. One that won't make me look like Humbert Humbert.
