Tonight on my way home, I was happy to see that the train was mostly empty (since on Mondays and Wednesdays I’m in an epistemology seminar until well after rush hour). At the next stop, though, this guy sits down directly across from me and immediately starts picking his nose. We’re talking a finger in up to the knuckle, that kind of thing. So I moved to the other end of the car. Then at the next stop a woman sits down across from me at that end and starts flossing. Flossing, on the train. These are times when it’s better to just crank up the iPod and pretend to be asleep, I think.
