It's late night. You're waiting in the subway station to go back home. There is a creepy group of men staring at you, 20 feet from where you stand, and they start walking menacingly towards you. You take some steps back and bump into someone. You freeze in fear. You look over your shoulder and a tall man is glaring at the group and they stop walking. The group quickly retreat and you look over the man behind you again. "You okay?" He asks quietly.
