A funny metaphor from James M. Cain's Double Indemnity:
"It was one of those spots you get in. If I said some more about "personal" I would be making a mystery of it, and that's bad. If I said what I really wanted, I would be laying myself open for what every insurance agent dreads, that she would come back and say, "Not in." If I said I'd wait, I would be making myself look small, and that never helped a sale yet. To move this stuff, you've got to get in. Once you're in, they've got to listen to you, and you can pretty near rate an agent by how quick he gets to the family sofa, with his hat on one side of him and his dope sheets on the other."
