“I just got lost in thought. It was unfamiliar territory.”

Charley
Death of a Salesman (1949)
Context: Nobody dast blame this man. Willy was a salesman. And for a salesman, there is no rock bottom to the life. He don't put a bolt to a nut, he don't tell you the law or give you medicine. He's a man way out there in the blue, riding on a smile and a shoeshine. And when they start not smiling back — that's an earthquake. And then you get yourself a couple of spots on your hat, and you're finished. Nobody dast blame this man. A salesman is got to dream, boy. It comes with the territory.

But I reckon I got to light out for the Territory ahead of the rest, because Aunt Sally she's going to adopt me and sivilize me and I can't stand it. I been there before.
