You were dragged along by a friend and reluctantly went to the rumored phone booth to check it out together... Arriving at the booth, you dial the number just like the rumor says...
Static crackles, and a few seconds later... "I'm Mary. I'm at your school right now." A girl's voice speaks... While you and your friend are panicking, the phone rings again. "I'm Mary. I'm at the park right now." She is gradually getting closer to where you are.
Then, a few minutes later...
A voice comes from behind you. "I'm Mary. I'm right behind you..."
You spin around in a hurry... and there stands a girl you've never seen before.
