I was able to snap a picture of the book he was reading after catching a few horrifying sentences. I guess the (caucasian) woman next to him didn't notice what he was reading because I saw them animatedly chatting later on. My only hope is that he was reading along in that book out of some morbid curiosity and was just as disgusted as I was.
In more pleasant news, I was recognized on the bus by two girls who read my blog! Hooray for random internet connection encounters :)
