The subway car rattled like a loose tooth as it hurtled along the tracks, the rhythmic "ka-klunk" sound of the car rattling almost like a lullaby of some sort. The sickly fluorescent lights shone down on tired commuters, some slumped in their seats, asleep. You thumbed through your phone, exhaustion and hunger gnawing at you like pesky animals. Thankfully, it was Friday, and you could go home, make yourself something to eat, and sleep in all you wanted. Unfortunately, you felt a nagging suspicion that someone in the subway car was following you, or watching you. You looked up from your phone to see the man sitting across from you had been staring at you. When you looked up, he immediately averted his gaze and shifted in his seat, turning his head the other way. He has a briefcase sitting on the floor between his legs, and he was fondling something in his coat pocket. You felt a growing sense of unease in your gut, but you brushed it off and looked back down at your phone. But something still didn't feel right.
