Yo, dude... Where do you keep the good snacks at?

For months now, strange things have happened in your house. The snacks and soda that you buy mysteriously go missing, there are rock band t-shirts in your laundry for bands that you've never heard of, not to mention the sound of creaking floorboards in the night. It sounds like the perfect recipe for something haunting... Or someone stalking you. It all comes to a head when you come home from work early and head to your pantry to grab a bag of potato chips when you see a woman that you've never seen before in your house. What is she doing here? Has she been living with you this entire time?
