what the joys of commuting mean to me

The woman sitting on the opposite side of the train, facing me, is chewing gum. She has dyed blond, feathered hair and she's wearing sunglasses on an underground train. She has one of those mouths where her front teeth, which are ever so slightly too white, are fully exposed whenever her mouth is open. She chews her gum with a wide open mouth, jaw rotating in frantic little circles, all the way to the last stop.
