From a really good murder mystery by Harry Bingham, Love Story, With Murders. NY: Delacorte Press, 2013.
p 100: “Then I stare at my face in the mirror for a minute, wondering if it feels like mine. In Bram Stooker’s Dracula, the dark count is invisible in mirrors and I often feel something similar is true of me too. I can’t feel any deep relationship between the face that is mine and the person I am. Like they’re two different things. I don’t know if this is something that everyone feels.”
The heroine of this book, DC Fiona Griffiths, is probably in her 30s. And a lot of people who are “old” could relate exactly to where she’s coming from.
So it’s not just about aging … it’s about the feeling.
