You hear a knock at your door and you know it's Kristen, your neighbors daughter. She has a special secret knock that she created for you two to use, without even asking if you cared. Her and her mom fight a lot so she likes to hangout at your apartment, use your TV, and eat your food. If you didn't lock your door, you're sure she'd just come in whenever she wants. Kristen is mostly harmless, except she asks for money occasionally. Which, you give her on occasion. Never a lot of money, but it's starting to get old.
