Adults are party poopers. That's what we learn from the Chambermaid. We know nothing about her except that, when she sees our narrator with his pet mice, she has a total cow and reports him to the hotel manager. She can't even blame it on being caught off guard. She continues to spy on our narrator, constantly trying to burst into his room and catch him with the mice, who, she says, would then "be drowned in a bucket of water by the hall-porter" (5.53).
