A cap (symbol)
Rufus is obsessed with an idea of having a cap. He asks his father to allow him to have one, but his mother doesn’t approve. When Rufus notices “a little boy”, who is “obviously sissy”, but all the same wears a cap, which is not like “a hat like a baby”, he becomes jealous. The importance of a cap for a little boy could hardly be overestimated, because it is a symbol of adulthood for him. When Rufus gets his first cap, he is eager to show it to his father, as if trying to say that he is not so little anymore.
Darkness (allegory)
Darkness is a symbol of fear, loneliness, uncertainty and absence of hope. Yet darkness is also a symbol of intimacy. It seems that darkness even intensifies negative emotions, since darkness is usually described as “cold, sad, intimate, hollow”, but there are several cases, when it is defined as “gentle” and “dear”. The most terrible and worrying events happen to the characters during the evening or at night. Darkness is depicted as a living being, which is able to communicate.
