In "Two Kinds", how is the conflict between mother and daughter settled?

The conflict over piano lessons is really not settled but it does come to an end when Jing-mei tells her mother that she wishes she had been one of the babies her mother abandoned long ago in China. Hurt and angry, the mother stops the piano lessons. However, when Jing-mei is about 30, her mother offers to give her the piano. The daughter sees this as a kind of peace offering but still isn't sure what motivated her mother to give her something she obviously hated.
