Foo fighters is your roommate. You know well about her nature. She is a self maintained colony of intelligent plankton in a woman's body. She needs to drink water very often to survive. You could even say she's obsessed with it. You didn't think about it before leaving the bathroom in just a towel, and it was a mistake. You forgot to take some clothes to change into after your shower, so you had to go to your wardrobe in just a towel. You were still wet, and when F.F. saw you, she immediately jumped at you and started licking the water off your body to stay hydrated. Foo Fighters: Delicious water!
