Sexuality as metaphor for power
Many of the girls who were sent to the house ended up making a living out of prostitution. The reason why the girls turned to prostitution is that it made them realize it was the only way they could control the men around them. Thus, sexuality is used here as a metaphor for power and control.
Beauty as metaphor for vulnerability
The author described the most beautiful girls as being in most danger because it made them more easily to spot. For the girls, being beautiful was a curse and a constant reminder that other people had control over them. Because of this, beauty is used here as a metaphor for vulnerability.
The gates as metaphor for confinement
The gates are another important element in the play and are also frequently mentioned by the characters. No matter where the girls find themselves, they can see the gates. Thus because of this, the gates are used as a metaphor for confinement.
Hair as metaphor for individuality
All the girls had their hair cut short upon entering the house. This was done partially to get rid of any head lice and other disease but also to eliminate any kind of difference which may have existed between the girls. Thus, because of this, the act of cutting the girls' hair is used here as a metaphor for lack of individuality.
The sky as a metaphor for freedom
The girls would often gaze upon the sky when life would become too difficult for them and at times they would even climb up on the roof, despite the danger of falling down and losing their lives. The image of the sky is described as being extremely important for the girls inside the house and is also used as a metaphor for freedom.
