I think that one of the most pointed and specific lessons that Hannah learns as a result of her experience is not take her ancestry for granted. At the start of the novel, Hannah shows little regard for being Jewish. Hannah shows little respect for the Judaic traditions in which her family believes and shows a begrudging token regard for what it means to be Jewish. Her experience changes her as she understands about a time in history when being Jewish translated into so much suffering and pain. The traditions and practices that she now takes for granted is something that her experience in time travel will validate, enabling her to have more regard for her ancestry and the people who sacrificed for it. In having more respect for her ancestry, Hannah will be able to learn the lesson of priorities and showing respect for that which is the ultimate definition of identity. At the same time, the novel suggests that Hannah learns that to be Jewish is something that must be lived with pride and zeal because the modern generation is the benefactor of the sacrifices made by the past generations. Hannah benefits because of Chaya and with this, both have a newly validated voice.
