Answer:
The central idea of "In the House With No Doors" by Sarah Kay is the struggle with grief and the different ways in which people cope with it. The poem describes a house with no doors where a family lives, and how they have each found their own ways to deal with the loss of their loved one. The speaker portrays a sense of confusion and loneliness, as she tries to navigate her own feelings of grief and tries to understand the various ways in which others are coping. The poem suggests that grief can be a complex and difficult emotion to deal with, but that finding ways to connect with others and share experiences can help people to find comfort and move forward. Ultimately, the central idea of the poem is that grief is a universal experience that can be shared and that it is important to seek support from others when going through difficult times.
