“That makes me want to cry, the idea of having a long relationship with adult children,” she toldTracee Ellis Rosslast year. “I never expected the kind of relationship that I have with them, but it’s so rewarding to be able to have kids that you can process life with a little bit, and they help me understand the complexities of what it means to be a human now.
