Shift change, no sun

My coworkers and I rotate three shifts. This week, I start at 7:00am. That means I'm on the 6:00 train. It's dark, cold and lonely. However, the train is sparce and you rarely ever hear some jackass yelling into their cell phone; I suppose that's a perk. Who doesn't know that action is second only to fingernails on a chalkboard on the agony meter?!
