The mention of children reflects the end of the novel, which focuses on young kids. Most of the characters are concerned with youth -
recapturing their energy from younger days, or trying to live their youth as fully as possible before it goes away. Sasha's teenage years were troubled, but later in life she finds peace providing for her kids. This reflects how children are hope for the
future - while adults might feel stuck in their ways, children hold the potential to change the future.
