“I thought it was normal, that’s the thing. When you’re little you think everything is normal. If your mother had a pointed head and green ears you’d think it’s normal. Only when you grow up do you realise that not everybody is like that. Gradually you can even come to learn that the time you are living in is strange too, that it hasn’t always been like this. The more you feel uncomfortable and unconfident and want to find a way to be like everyone else and fit in, the more normality runs away from you because there isn’t any such thing. Or if there is, you have to find someone else who’ll agree with you what it is. Which I seem singularly unable to do.”

Jeremy Marsh, Chapter 7, p. 113
Variant: I think it happens to everyone as they grow up. You find out who you are and what you want, and then you realize that people you've known forever don't see things the way you do. And so you keep the wonderful memories, but find yourself moving on. It's perfectly normal.
