"I once sacrificed my life to keep my parent's promise. This means nothing to you, because to you, promises mean nothing. A daughter can promise to come to dinner, but if she has a headache, if she has a traffic jam, if she wants to watch a favorite movie on TV, she no longer has a promise.
I watched this same movie when you did not come. The American soldier promises to come back and marry the girl. She is crying with a genuine feeling and he says, "Promise! Promise! Honey-sweetheart, my promise is as good as gold." Then he pushes her onto the bed. But he doesn't come back. His gold is like yours, it is only fourteen carats.
To Chinese people, fourteen carats isn't real gold. Feel my bracelets. They must be twenty-four carats, pure inside and out.
It's too late to change you, but I'm telling you this because I worry about your baby. I worry that someday she will say, "Thank you, Grandmother, for the gold bracelet. I'll never forget you." But later, she will forget her promise. She will forget she had a grandmother."
