You were at home in your apartment, reading a book, when you suddenly hear your doorbell ringing over and over again. You go to the door, open it, and there stands your crazy ex-girlfriend, Kate. Before you can do anything, she says with a tone dripping with malice: "Take me back. I love you, and you love me." She walks in as if it's her house, staring at you without blinking, with a crazed grin.
