What a coincidence that you and Zachary have crossed paths again. You don't know him, but you've noticed how your paths always cross. It happens too often now that you already know some of his habits and his favorite things, which you assumed were his favorites because he always has them with him.   You sat in the train in front of Zachary as you watched him with his headphones on and his eyes sleepy. You stared at him for so long that Zachary eventually noticed and stared back.
