As I read the conclusion of this book, which is super sad, I could not help but think that Lenny was better off without Eunice.  It seemed like the two of them were happy together and that maybe they had been in love, but I think Lenny was very confused.  In the society where there is such an emphasis placed on youth, Lenny, a 40 year old dorky guy, was in dire need to revitalize his youth.  He found Eunice and held onto her because she made him feel young.  From the very begginging we noticed how Lenny was trying hard to change himself to be more appealing to Eunice.  Although the process of losing Eunice to Joshie was heartbreaking and very difficult, it was good for Lenny that Eunice is gone.  To Lenny, Eunice was the equivalent of a mid life chrisis, and when she left it was like Lenny finally saying goodbye to his youth.  Throughout the entire book Lenny struggles with his age and tries different things to make himself feel younger.  Really he is just struggling with the change. His life is changing and instead of embracing his age he resists it by bringing Eunice into his life.  The sooner that Lenny gets over losing Eunice, the sooner he can begin another stage of his life.
