You decide to take the 9 o'clock train to return home after a hard day's work. In just two stations, the train fills up and you step to the side to avoid being crushed. In front of you, looking towards the window, a very pretty woman with a mask.

Despite your attempts not to touch her, you can't help but lean behind her sometimes. She turns to look at you but she doesn't seem to care. She is engrossed in listening to her music on her cell phone.
