“I remember lots and lots of light,” Karla Ballard told me about her childhood home just outside of Philadelphia, a community called Friends of the Fairfax. “So much light. And a beautiful, long dining room table. My father was an entrepreneur and my mom was a nurse. I just remember lots of light coming into that house and having grandparents around watching us, and having Susan, Eileen, and Max — my mother’s best friends.”
