Brod, a character in "Everything Is Illuminated," experiences profound emotional turmoil but is wary of expressing her feelings. The walls of her old house symbolize both physical and emotional barriers; she fears that showing vulnerability, such as crying, might lead to instability or destruction. Instead of allowing her emotions to surface, she chooses to repress them, creating a hidden sanctuary for her feelings where they can remain undisturbed.

This choice to "sandbag" her tears highlights her inner conflict and struggle with vulnerability. Rather than confronting her emotions directly, Brod opts for exile, illustrating the tension between the desire to express her grief and the fear of the consequences that may arise from it. Through this metaphor, Foer emphasizes the complexities of human emotion and the lengths individuals may go to protect themselves from pain.
