In this paper, three discourse strategies are presented in writing parent’s autobiography. First, as the interviews are being conducted, the parent's autobiography written by children should be a past discourse in which their parent's life is mainly focused on. And when they are writing, a chronical describing is offered to describe their parent's course of growing. The contents of growing discourse should include such things as their parent's childhood, adolescence, youth, adulthood, and senior stories about his or her parents. Second, parents and children should discuss a parent's life and after that, they speculate on the life of a parent, which makes them rethink about how it has affected their lives in appreciation or resentment. Thus, writing parent’s autobiography is describing present. One way to implement mechanism of speculation discourse is that parents write some notes first on the marginal page of the autobiography their child has written, then, the child has only to write his or her own feelings about them. Lastly, writing parent’s autobiography makes the relationship between parents and children restored and allow them to make the future discourse together. Beyond ‘You’ and ‘I’ calling each other ‘We’, they will record future plans in the autobiography restoring the family relationship.
