Hi there. Thank you so much for saying that. I answered a variation on this above, but I'll add here that a friend of mine says this: "Middle-age is when I say it is, and I say it's 10 years older than I currently am, in perpetuity." I wrote the book when I was 41. I wanted everyone to be 41. But actors act, and we got to not just have people who played their own flashbacks, but also people we generally all grew up with. It was amazing to see how moving it was to see your own aging through the fact that you've been watching Claire Danes since she was a high school student and Jesse Eisenberg since he was a kid, etc. etc. - Taffy
