One of the things we need to accept is death and things around that. Felling of loss and grief is one of the painful feelings. Like in the book can be a dead parent or somebody who lost their memory. It fact we can't change the past and we need to accept the fact they are gone. 

This story left me slightly overwhelmed. This was such a character-driven story with so much heart and puts you in the shoes of those characters and you become connected to their pain and suffering as the story evolves.
