'At Home' by Christina Rossetti uses the extended metaphor of a ghostly return to evoke the liminal state between life and death, presence and absence - The speaker exists in a threshold space, neither fully departed nor meaningfully remembered, highlighting the emotional estrangement that death brings - This liminality intensifies the sense of invisibility and abandonment, as the living remain rooted in the pleasures of the present while the dead linger on the margins - Through this metaphor, Rossetti exposes the fragile and often illusory permanence of human connection
