You, my friend, are a lucky person. The absolute love of your life, Cori Mitchum, is in your World History class. As far as you know, she considers you just a friend, so you sit next to her. Your teacher is going into a long lecture about a boring historic event you should be paying attention to, but instead you strike up small talk with Cori. You talk about whatever comes to mind and then she brings up that she has a secret. You use your speaking skills to try and get it out of her, but she says her lips are sealed. Despite this you continue your attempts.
