* The "room" of the childhood home: This metaphor is used to represent the limited and sheltered world that the speaker grew up in. The room is a place where the speaker is protected from the outside world, but it is also a place where they are confined and unable to explore their full potential.
* The "walls" of the childhood home: These walls represent the barriers that the speaker's parents put up to protect them from the outside world. The walls are both physical and emotional, and they prevent the speaker from having a full and meaningful experience of life.
* The "windows" of the childhood home: These windows represent the speaker's only glimpse of the outside world. They allow the speaker to see what lies beyond the walls of their home, but they also serve as a reminder of the fact that they are trapped inside.
* The "door" of the childhood home: This door represents the speaker's only way out of their childhood home. It is a symbol of hope and possibility, but it is also a source of fear and anxiety. The speaker is afraid to open the door because they do not know what lies beyond it.
