Ironically, I heard Nora Ephron say this at a “Women in Hollywood” panel almost ten years ago. (I say “ironically,” because she didn’t love doing those.) Someone asked what she’d learned from her parents, and this was her response.
**UPDATE: Turns out EVERYONE knows Nora Ephron said this. I thought I had some delightful, unique insight, because it’s the only thing I remembered from that event.
