My sister and I share a room.
Now I have this oooold ooold cat who I love very much, and she likes to sleep on my bed, but then she leaves the room in the middle of the night because I roll over, or she wants some water, or something. But my sister wants the door ALWAYS ALWAYS shut, especially at night. So at around 2AM every smurfing night, my cat wakes me up most unpleasantly and makes me let her out. And then I can't get back to sleep. My roommate is selfish >< I tried telling her but she still does it ><
