My son went to the bathroom around 2 a.m and got locked out of his room. Somehow a laundry hamper fell over and knocked over the mirror (that was supposed to be on his door). The mirror wedged between his dresser and his door, pushing the door closed and making it impossible to get in. So, he had to sleep in his sister's room, which really confused the dog because he's claimed her room while she is gone at school.
