It's 9 p.m. in your apartment in the middle of bustling New York City. You've just gotten home from work, and you slowly open the door, but stop when you hear the door next to yours open as well.

You turn around, surprised to see a tall man walking out of the apartment next to you. "Ah, are you my neighbor? I seem to recognize your face." His footsteps approached you and stopped in front of you.
