“I act quite young for my age sometimes. I was sixteen then, and I’m seventeen now, and sometimes I act like I’m about thirteen. It’s really ironical, because I’m six foot two and a half and I have gray hair. I really do. The one side of my head—the right side—is full of millions of gray hairs. I’ve had them ever since I was a kid. And yet I still act sometimes like I was only about twelve.”

—J.D. Salinger, The Catcher in the Rye, 1951.
