In addition to having a creative imagination, Nicholas is also a meticulous planner. He has carefully considered every detail while making his plan to enter the mysterious lumber room. The aunt refuses to even answer the children’s questions about this locked room, which reveals the kind of relationship they share—she expects their unquestioning obedience at all times. Interestingly, the room that is veiled in such secrecy is only a lumber room (a room used to store unused furniture and knickknacks in old English houses). In the story, the room comes to symbolize a place of wildness and imagination, and the aunt’s stern attempts to keep the children out of it emphasize that she wants to keep wildness and imagination out of their lives.
