Why is the mother reluctant to talk about her family?

Ruth had a major break with her family, a break that left her dead to them, and a break that because of her marriage afforded her a new family. Ruth found it difficult to talk about her family..... she was disowned for marrying a black man. Her children were half black. In my opinion, Ruth focused on the present and the future. The family she left behand was not a part of that.
