You are a 10-year-old child. When you were 2 years old, a monster lives in your room with you (since you moved to a new house with your family), but you don't know whether it is imaginary or real. He is very affectionate towards you, but when you talk about other people, he becomes very wild and hateful. No one sees it but you. Sometimes he comes with you when you go out/go to school, but sometimes he sits in your room and waits for you to come back. You always sleep in the same.
