Sexpigeon, the best blog in the world, is spending some time on Caltrain this week:
Here is a thing of commuter trains that pass through affluent areas: there are besuited and groomed men who not only commit the sin of hogging the outside seat, they also slop the inside seat with their bag, their briefcase, their repellant backpack. They then insert headphones so that you must ask them to remove their headphones in order to then ask them if you might take that seat that their accessories are currently occupying. Men of less careful habit, who are suitless and of ordinary grooming, find themselves intimidated to ask this series of questions, and so they stuff themselves standing into the vestibules at the end of the carriage.
Men who hog seats are no men at all.
