Probably on of the most dehumanising things about transit, aside from being herded like cattle into large tin cans with wheels, is living in bizarre fractions of an hour. You find yourself thinking things like, "Oh, crap: it's 7:13! I'll never make it to the corner for the 7:37, but with luck the 7:43 trian will get me to the 8:22 bus so I'll only be 6 minutes late."
